CONTROL OF AC SERVO MOTOR USING FUZZY LOGIC

Abstract

The goal of adaptive control is to adjust unknown or changing plant parameters. This is accomplished by either changing parameters in the controller to minimize error, or using plant parameter estimates to change the control signal. In this study the basic idea is use the fuzzy logic controller with refer to Proportional Integral Derivative( PID) method. The choice of the fuzzy logic is based on its main feature; that its logic flow approaches real time situations more than most of the other known algorithms. The idea of perfection is to provide an even more smooth control to the AC servo motor and to minimize deficiencies of the traditional Proportional Integral Derivative( PID) method. This study deals with the conventional PID and replaces it with fuzzy controller. The performance of the drive system obtained, formed a set of test conditions with fuzzy controller. This study also compares the performance of fuzzy controller over conventional PID controller. To achieve these objectives the simulation environment is provided in the MATLAB Simulink
