The self-adjustable fuzzy sliding mode control for AC speed drive systems
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000The paper deals with a novel method, self-adjustable fuzzy sliding mode control, of a squirrel cage induction motor drive systems with a voltage source inverter. According to the principle of fuzzy logic control and sliding mode control, the theory of this new fuzzy sliding mode control is presented and a mathematical description for induction motor is

Application of Self-adjusting Quantitative Factor Fuzzy Controller in Tank System
2009For normal fuzzy controllers can’t provide perfect effects when it is used to control the water tank system, this paper adopts a self-adjusting quantitative factor fuzzy controller to deal with this problem. The effects indicate that this controller has the characters of responding quickly, small overshoot and less static errors, and it is practicably ...

Searchless Self-Adjustable Adaptation and Control Systems
2002The problem of identification and estimation of unknown parameters is one of the most important problems of control theory and practice. However the difficulty of realizing identification procedures consists for one thing in the impossibility of performing a direct parameter control in conditions of uncertainty.

A self-adjusting computer process control system for chemical pulp refiners
IFAC Proceedings Volumes, 1977In this ADAPT-SET system, which was put into real-time environment in June 1976, the control policy is to keep the “per unit” energy and the “specific edge load” which characterize the refining operation at their set-point values. The selection of operating points is less restricted using this method than using conventional methods where only the ...
