Simulation of Expert Self-adaptive PID Control System for
Brushless Doubly-fed Machine

Abstract

Abstract: The application of expert self-adaptive PID controller in Brushless Doubly-Fed Machines （BDF M） for adjustable speed drive was presentedthe simulation model of the control system based on MATLAB／Simulink was also establishedthen the simulation experiments under the conditions of startup and steady-state were carried out．The results show thatcomparing with open-loop conditionthe static and dynamic performances of the system are improved greatly by using the controllerand the overshoot of the machine decreases when the rotating speed or the load changes．The scheme proposed here is a simple and convenient closed-loop control strategy for BDF M drive．

Key words: Brushless Doubly-fed Machine, self-adaptive control, expert system, PID control
