Robust Control for Uncertain Nonlinear Feedback Systems Using Operator-based Right Coprime Factorization

The robust control issue for uncertain nonlinear system is discussed by using the method of right coprime factorization. As it is difficult to obtain the inverse of the right factor due to the high nonlinearity, the proving of the Bezout identity becomes troublesome. Therefore, two sufficient conditions are derived to manage this problem with the nonlinear feedback system as well as that with the uncertain nonlinear feedback system under the definition of Lipschitz norm. A simulation of temperature control is given to demonstrate the validity of the proposed method.

THE OPTIMAL CONTROL OF DELAY CONTROL SYSTEMS WITH RESTRICTED STATE RIGHT ENDPOINT

In this paper, for the delay control system: (x) over dot (t)=f[x(t), x(t-1), u(t), t] t is an element of[t(0), t(1)] x(t)=psi(t) t is an element of[t(0), t(1)] with state right endpoint restricted by condition psi(k)[x(t(1))]=0 (k=1,2,..., l) a maximum principle is given. And as a specific example, this paper gives a maximum principle under the condition that partial stares right endpoints be completely fixed. Finally, this paper gives an example to explain the application of the main result of this paper. All the results are suitable for the control systems with multidelay as well.

The Limits of the Intervention of Public Power in Individual Health Choices——From the Perspective of the Realization of the Right to Health in the Prevention and Control of Chronic Diseases

Noncommunicable chronic diseases have become the most important public health problem in the world today,so the focus of public health services should be shifted from the traditional area of communicable diseases to the prevention and control of chronic diseases.Since bad living habits are the most direct cause of chronic diseases,the most effective measure to prevent and control chronic diseases is to promote healthy lifestyles for the individual citizen.The theories of equal health opportunity,the right to health from the perspective of human rights,and determinants of a healthy society provide justified reasons for the intervention of public power in individual health choices.In the current legal system,the intervention of public power is limited to flexible measures such as health education,which shows respect for individual autonomy.However,it is inconsistent with the needs of current public health practice.We should expand diversified intervention means to encourage individuals to make healthy choices under the guidance of the management model.The“ladder of intervention”outlines a panoramic view of the intervention measures available.However,for the selection of specific measures,it is necessary to consider the public health objectives and the invasion of individual freedom,introduce the“legal reservation principle”and“proportionality principle”as policy analysis tools,and reasonably choose intervention measures at different levels on the ladder to properly handle the tension between public power and private rights.

Digital Rights Management：Model,Technology and Application

with rapid achievement of current information technology and computing ability and applications,much more digital content such as films,cartoons,design drawings,office documents and software source codes are produced in daily work,however to protect the content being copying,shared or deliberately stolen by inside or outside,digital rights management(DRM) became more and more important for digital content protection.In this paper,we studied various DRM model,technology and application,and first proposed DRM Security Infrastructure(DSI),in which we defined encryption,hash,signature algorithm,watermarking algorithms,authentication,usage control,trusted counter,conditional trace,secure payment,and based on the DSI we then proposed a whole classification approach and architecture of all kinds of DRMs,in which we proposed 6 typical classes of copyrights and content protection DRMs architecture:(1) Software-oriented DRM,(2) e Book-oriented DRM,(3) Video-oriented DRM,(4) Image-Oriented DRM(5) Unstructured data oriented DRM,(6) Text-oriented DRM.Based on the above DSI,we then proposed a dynamic DRM model selection method for various DRM application,which can be adapted dynamically for different technology of different applications,which can provide awhole solution for variant DRM development in a rapid and customized mode.The proposed DRM method,technology and application in this paper provided a common,flexible and extendable solution for variant DRM scenes,and can support rapid and customized development.Moreover,we proposed an opinion that the future life will enter into a new era that the content usage and consumption will not again adopt DRM technology rather than with law,liberty and morality.

Attribute Based DRM Scheme with Dynamic Usage Control in Cloud Computing

In order to achieve fine-grained access control in cloud computing,existing digital rights management(DRM) schemes adopt attribute-based encryption as the main encryption primitive.However,these schemes suffer from inefficiency and cannot support dynamic updating of usage rights stored in the cloud.In this paper,we propose a novel DRM scheme with secure key management and dynamic usage control in cloud computing.We present a secure key management mechanism based on attribute-based encryption and proxy re-encryption.Only the users whose attributes satisfy the access policy of the encrypted content and who have effective usage rights can be able to recover the content encryption key and further decrypt the content.The attribute based mechanism allows the content provider to selectively provide fine-grained access control of contents among a set of users,and also enables the license server to implement immediate attribute and user revocation.Moreover,our scheme supports privacy-preserving dynamic usage control based on additive homomorphic encryption,which allows the license server in the cloud to update the users' usage rights dynamically without disclosing the plaintext.Extensive analytical results indicate that our proposed scheme is secure and efficient.

Study on Water Pollution and Control in China

In recent years, water pollution has become increasingly serious in China. Meanwhile, decrease of water bodies in quality, frequent pollution incidents, safety of drinking water and water shortage have become prominent day by day. However, water pollution can not be controlled effectively. To clear underlying reasons for increasingly worsening water environment, the external effects of pollution behavior and fictitious property right of pollution control bodies were analyzed using property right theory, and then internal reasons for serious water pollution were discussed. Fi- nally, control measures of water pollution were put forward.

Review on the Study of the Allocation of Corporate Control in Enterprise Theory

With the establishment of a modem corporate system, the separation of ownership and management appears in the company. The rational allocation of corporate control between different behavioral agents has attracted more and more attention. This paper points out that scholars have studied the allocation of corporate control from the angles of the agency cost theory, property rights theory, corporate finance theory, and the theory of corporate governance, which has great value. However, the existing theories also have some flaws on the allocation of corporate control. First, people still have different understandings and views over the meaning of corporate control. Secondly, the existing research theoretically only observes and studies an arrangement of sheer level control, the allocation between final control and real control. This paper argues to build the two-tier allocation of corporate control： The first tier relation is between ultimate control rights and actual control rights, the second tier relation is between indirect control rights and direct control rights which are in actual control rights. This study can explain the resource allocation effects of corporate control, promote the development and improvement of the theory of the firm.

ROBUST SMITH PREDICTIVE CONTROLLER FOR PROCESS WITH INVERSE RESPONSE

Smith predictor known as the time delay compensator was extended to control the process with inverse response.Modern robust control theory was employed to design the robust controller,which has only one parameter to be determined with compromise among the rise time,undershoot,robustness and capability to reject disturbance of the closed loop system.The former two specifications can be assessed quantitatively and the latter two qualitatively.Examples show that the proposed method has significant improvements and wide applicable ranges for inverse response process.

Operator-Based Robust Nonlinear Control for SISO and MIMO Nonlinear Systems With PI Hysteresis

In this paper, operator based robust nonlinear control for single-input single-output(SISO) and multi-input multi-output(MIMO) nonlinear uncertain systems preceded by generalized Prandtl-Ishlinskii(PI) hysteresis is considered respectively. In detail, by using operator based robust right coprime factorization approach, the control system design structures including feedforward and feedback controllers for both SISO and MIMO nonlinear uncertain systems are given, respectively.In which, the controller design includes the information of PI hysteresis and its inverse, and some sufficient conditions for the controllers in both SISO and MIMO systems should be satisfied are also derived respectively. Based on the proposed conditions, influence from hysteresis is rejected, the systems are robustly stable and output tracking performance can be realized.Finally, the effectiveness of the proposed method is confirmed by numerical simulations.

Is a Human Right to Democracy Justifiable？

In this article, I examine the view that there is a human right to democracy, and consider why we should regard this issue as decisive in solving the problems of foreign interference in the protection of human rights. I also note that there has been almost no discussion about the holder of the human right to democracy, that is, who is to hold this right. After comparing John Rawls＇ argument against the human right to democracy and Thomas Christiano＇s argument for it and showing similarities and critical differences among their arguments, I insist that we ought to be sensitive when proclaiming that democracy--be it a minimally egalitarian democracy or a more exacting one--is a universal value. We have sufficient cause to consider carefully not only the political circumstances but also the political infrastructure of the country before we proceed to an even limited intervention in the name of the protection of a human right to democracy. If the human right to democracy is not just a right to vote, but a right to the whole process of establishment and enjoyment of democracy, it should be understood as a group right that pertains to a human population that legitimately claims political self-determination. Any human population that insists on the democratic self-determination of their political will is both able and entitled to establish and administer democratic institutions, regardless of the diversity of its ascribed or cultural characteristics. The establishment of such a group with a firm political identity should be considered as the political infrastructure to claim and exercise the human right to democracy.

Fuzzy Logic Controller Implementation of Power Quality Improvement Using UPQC

This paper presents a gross examination about Unified Power Quality Conditioner (UPQC) to invigorate the power issues at the distribution level of the electrical system. Nowadays power electronics research has added the importance of power quality studies, for concrete illustration, Custom Power Devices (CPD) and Flexible AC Transmission position (FACTS) devices. The approach offered in this paper utilizes the series and shunt compensator of Unified Power Quality Conditioner (UPQC) to inject a compensation voltage in-phase with the source current over voltage fluctuations. The execution of two structures of UPQC, left-shunt (L-UPQC) and right-shunt (R-UPQC) are investigated under diverse operating conditions based on the fuzzy logic controller to raise the value of power quality of a single feeder distribution system by MATLAB/Simulink programming. Various power quality issues have been analyzed in this study. Finally, the right shunt UPQC is outperformed in this proposed power system.

Third-Generation Human Rights＂ A Tragic Illusion

This paper deals with the applicability of human rights in general and of third-generation human right in particular. It offers an explanation of the pathetic status of human rights and suggests an alternative approach towards ＂third-generation＂ human rights, i.e., the rights of communities. It argues that since an immanent dichotomy exists between the political aspect of human rights--the fact that their addressee is the state government--and their universal aspect, i.e., the fact that they belong to everyone and their fulfillment is demanded by international bodies, very often their possessors cannot capitalize them. Third-generation human rights encounter additional problems. Very often their respondent--the state government----cannot comply with their demands, and according to the Kantian principle ＂Ought Implies Can,＂ they should be addressed towards someone who can in fact fulfill them. This article thus suggests addressing third-generation human rights towards the international community. This may exclude them from the current category of human rights, and create the need to establish a new category such as Community Rights. Such classification may bear the advantage of making these rights more applicable and accessible than they are at present.

Geospacial information utilized under the access control strategy

This paper introduces a solution to the secure requirement for digital rights management （DRM） by the way of geospacial access control named geospacial access control （GeoAC） in geospacial field. The issues of authorization for geospacial DRM are concentrated on. To geospacial DRM, one aspect is the declaration and enforcement of access rights, based on geographic aspects. To the approbation of digital geographic content, it is important to adopt online access to geodata through a special data infrastructure （SDI）. This results in the interoperability requirements on three different levels： data model level, service level and access control level. The interaction between the data model and service level can be obtained by criterions of the open geospacial consortium （OGC）, and the interaction of the access control level may be reached by declaring and enforcing access restrictions in GeoAC. Then an archetype enforcement based on GeoAC is elucidated. As one aspect of performing usage rights, the execution of access restrictions as an extension to a regular SDI is illuminated.

Quasi Controlled K-Metric Spaces over C^(*)-Algebras with an Application to Stochastic Integral Equations

Generally,the field of fixed point theory has attracted the attention of researchers in different fields of science and engineering due to its use in proving the existence and uniqueness of solutions of real-world dynamic models.C^(∗)-algebra is being continually used to explain a physical system in quantum field theory and statistical mechanics and has subsequently become an important area of research.The concept of a C^(∗)-algebra-valued metric space was introduced in 2014 to generalize the concept of metric space.In fact,It is a generalization by replacing the set of real numbers with a C^(∗)-algebra.After that,this line of research continued,where several fixed point results have been obtained in the framework of C^(∗)-algebra valued metric,aswell as(more general)C^(∗)-algebra-valued b-metric spaces andC^(∗)-algebra-valued extended b-metric spaces.Very recently,based on the concept and properties of C^(∗)-algebras,we have studied the quasi-case of such spaces to give a more general notion of relaxing the triangular inequality in the asymmetric case.In this paper,we first introduce the concept of C^(∗)-algebra-valued quasi-controlledK-metric spaces and prove some fixed point theorems that remain valid in this setting.To support our main results,we also furnish some exampleswhichdemonstrate theutility of ourmainresult.Finally,as an application,we useour results to prove the existence and uniqueness of the solution to a nonlinear stochastic integral equation.
