Abstract:

In terms of nonlinear feature of asynchronous motor, it is considered difficult to adopt conventional proportional-integral-differential (PID) method to take effective control on the motor. A sort of controller via adaptive, PID and fuzzy method is then proposed and also applied to the speed regulation section. By using Simulink software tools in Matlab, a simulation model of fuzzy adaptive PID control for asynchronous motor is established. The computer simulation indicates the priority of the design which can be seen from that the overshoot and response of the system is reduced. The stability, dynamic responding and robust performance of the system are also improved comparing to the former control method of PID.
