A modification has been proposed in IMC-PID tuning rule for the improved disturbance rejection. For the modified IMC-PID tuning rule, a method has been developed to obtain the IMC-PID setting in closed-loop mode without acquiring detailed information of the process. The proposed method is based on the closed-loop step set point experiment using a proportional only controller with gain K_(c0). It is the direct approach to find the PID controller setting similar to classical Ziegler-Nichols closed-loop method. Based on simulations of a wide range of first-order with delay processes, a simple correlation has been derived to obtain the modified IMC-PID controller settings from closed-loop experiment. In this method, controller gain is a function of the overshoot obtained in the closed loop set point experiment. The integral and derivative time is mainly a function of the time to reach the first peak(overshoot). Simulation has been conducted for the broad class of processes and the controllers were tuned to have the same degree of robustness by measuring the maximum sensitivity, Ms, in order to obtain a reasonable comparison. The PID controller settings obtained in the proposed tuning method show better performance and robustness with other two-step tuning methods for the broad class of processes. It has also been applied to temperature control loop in distillation column model. The result has been compared to the open loop tuning method where it gives robust and fast response.展开更多

Curriculum used in school has a purpose to make learners be active and creative persons. It is an education plan that emphasizes the competency of learners. Indonesia, through its Ministry of Education, implements 2013 Curriculum officially that reflects the competency of learners. This curriculum is actually similar with competence-based curriculum which concentrates on learners. In senior high school level, English becomes one of the subjects of final national examination and also this is the last level for learners before they continue their study to university. International oriented school is a school that applies English as a second language and also a school cooperates with or uses international standard curriculum. Reflecting learning and teaching English in senior high school especially in the international oriented school is very important and needs special attention. This research investigates the implementation of curriculum in the international oriented senior high school in Yogyakarta. From the research, it is known that the school officially does not implement 2013 Curriculum. However, ACT （Assessment Certificate Test） curriculum and the values of the school automatically reflect the 2013 Curriculum because the school empowering implementation of competency-based curriculum in learning process that focuses on learner-centered learning, facilitating assessments of process of learning and fostering learners＇ autonomy through the curriculum is reflected in the school essentially in the programs and activities.展开更多

This study reports on the issue of comparing English language curricula by means of an institutional review in a northeast province in China in 2012. The study was essentially a qualitative inquiry with data collected online through documents submitted by the institutions and through semi-structured follow-up interviews. Thirty-seven participants from 12 institutions participated in the study. Research findings indicated that curriculum orientations varied across institutions and were reflected in their curriculum designs. Such a modus operandi, it is anticipated, may shed useful light on the understanding of curriculum reform currently being conducted in China in light of the rising demand for, and the needs of, internationalized and localized curricula, as well as providing an understanding of curricula at various institutions.展开更多
