Active suspension control of a one-wheel car model using single input rule modules fuzzy reasoning and a disturbance observer

This paper presents the construction of an active suspension control of a one-wheel car model using fuzzy reasoning and a disturbance observer. The one-wheel car model to be treated here can be approximately described as a nonlinear two degrees of freedom system subject to excitation from a road profile. The active control is designed as the fuzzy control inferred by using single input rule modules fuzzy reasoning, and the active control force is released by actuating a pneumatic actuator. The excitation from the road profile is estimated by using a disturbance observer, and the estimate is denoted as one of the variables in the precondition part of the fuzzy control rules. A compensator is inserted to counter the performance degradation due to the delay of the pneumatic actuator. The experimental result indicates that the proposed active suspension system improves much the vibration suppression of the car model. Key words One-wheel car model - Active suspension system - Single input rule modules fuzzy reasoning - Pneumatic actuator - Disturbance observer Document code A CLC number TH16

Pneumatic active suspension system for a one-wheel car model using fuzzy reasoning and a disturbance observer

This paper presents the construction of a pneumatic active suspension system for a one-wheel car model using fuzzy reasoning and a disturbance observer. The one-wheel car model can be approximately described as a nonlinear two degrees of freedom system subject to excitation from a road profile. The active control is composed of fuzzy and disturbance controls, and the active control force is constructed by actuating a pneumatic actuator. A phase lead-lag compensator is inserted to counter the performance degradation due to the delay of the pneumatic actuator. The experimental result indicates that the proposed active suspension improves much the vibration suppression of the car model.

Vehicular Electronic Image Stabilization System Based on a Gasoline Model Car Platform

Noise,vibration and harshness(NVH)problems in vehicle engineering are always challenging in both traditional vehicles and intelligent vehicles.Although high accuracy manufacturing,modern structural roads and advanced suspension technology have already significantly reduced NVH problems and their impacts;off-road condition,obstacles and extreme operating condition could still trigger NVH problems unexpectedly.This paper proposes a vehicular electronic image stabilization(EIS)system to solve the vibration problem of the camera and ensure the environment perceptive function of vehicles.Firstly,feature point detection and matching based on an oriented FAST and rotated BRIEF(ORB)algorithm are implemented to match images in the process of EIS.Furthermore,a novel improved random sampling consensus algorithm(i-RANSAC)is proposed to eliminate mismatched feature points and increase the matching accuracy significantly.And an adaptive Kalman filter(AKF)is applied to improve the adaptability of the vehicular EIS.Finally,an experimental platform based on a gasoline model car was established to validate its performance.The experimental results show that the proposed EIS system can satisfy vehicular performance requirements even under off-road condition with obvious obstacles.

Comparison of Generic Organization of the Research Paper in English and Polish： Cross-Cultural Variation and Pedagogical Implications

This paper provides a comparative analysis of the rhetorical structure and linguistic features of research papers written in English and Polish languages within the field of medicine. The study was based on a corpus of 30 research articles： 15 written by native English speakers and 15 by non-native speakers-Polish researchers. The outcomes of this investigation indicate some discrepancies in rhetorical structure between the research papers. An explanation for the cross-cultural differences which seem to be responsible for these discrepancies, and an enumeration of pedagogical implications for the use of a corpus-based approach to generic analysis in English for Specific Purposes （ESP） classes, are also provided.

Application of singular perturbation method in analyzing traffic density waves

Car following model is one of microscopic models for describing traffic flow. Through linear stability analysis, the neutral stability lines and the critical points are obtained for the different types of car following models and two modified models. The singular perturbation method has been used to derive various nonlinear wave equations, such as the Kortewegde-Vries （KdV） equation and the modified Korteweg-de-Vries （mKdV） equation, which could describe different density waves occurring in traffic flows under certain conditions. These density waves are mainly employed to depict the formation of traffic jams in the congested traffic flow. The general soliton solutions are given for the different types of car following models, and the results have been used to the modified models efficiently.

Success Story of Market Exploration of New Technology in China

Market exploration is always not easy. That of tailored-blank technology in China can not be an exception. After taking over the marketing and sales job of Andritz Soutec products, I spent the first 2 years promoting and pushing just the application of Tailored-blank technology. When the first project came, we unfortunately were confronting tough and ＂asymmetrical＂ competition. Even the management of Andritz Soutec intended to give up. My choice was ＂to still fight＂. After perseverance and great efforts, we finally concluded the first contract in China. As the Chinese saying goes ＂A good beginning is half of the success.＂ In the over 10 years after that, 57 Andritz Soutec Tailored-blank laser welding lines were sold in China market, which represents over 2/3 market share. For me it is one of the most successful stories.

The Two-person Double-price Second-hand Vehicle Trade Game Model of Quality Certification Market in China

The relation between two most important players, enterprises and certification bodies, of quality certification market are analyzed by building two-person game second-hand car trade model with two prices in this paper. By introducing a virtual player, the incomplete information game can be transformed into the complete but imperfect information game. Then some conclusions are given： there have two methods to make market succeed absolutely, （1） to eliminate the information＇s imperfection; （2） to increase the counterfeit cost. And by introducing the double-price second-hand car model with refundment guarantee of enterprises and certification bodies further, the author thinks it will increase counterfeit cost greatly to oblige certification bodies make actual quality promises and take on related liability to some extent. This kind of expensive commitment will make market succeed absolutely; accordingly it can increase and improve the effectiveness of quality certification, and the authority, justness and objectivity will be guaranteed further.
