Application of Fuzzy-PID Algorithms in Electric Actuator Control System

摘要

With its superior performance, electric actuator will gradually replace pneumatic and hydraulic actuators, and will become one of the most important features of the all-electric aircraft. The use of electric actuators such as power cable technology can effectively improve the mobility, reliability, maintainability, and duration performance of the aircraft. And it can solve the problem of the heavy hydraulic system simultaneously. This paper used TI's DSP expert engine control chip TMS320F28335 as the control core, one algorithm called Fuzzy-PID with adaptive performance had been applied to dual closed-loop control structure of brushless DC motor. The experimental results of the Fuzzy-PID controller was compared with that of the traditional PID controller, the dynamic performance of electric actuator servo system had got obvious improvement.
