Abstract

A fuzzy-immune PI speed regulator for vector control system of induction motor is designed, in which the proportion parameter is adjusted using the fuzzy-immune method and the integral parameter is adjusted using the algorithm of making the integrator desaturate in advance. The structure of the controller is simple comparatively, and it is convenient and effective to adjust its parameters. The simulation results show that the AC drive system has faster response, smaller overshoot and better robustness, and that the designed PI speed regulator improves the dynamic performance and the precision in AC drive system.
