Servo Motor Decoupling Control Based on PI Fuzzy Adaptive Method

Cao Xian-gang, Zhang Jian-bin


This paper introduced the permanent magnet synchronous motor mathematical model, using the vector control principle combined with decoupling control to effectively cancel out the rotating electromotive force in the motor model. Aiming at the traditional PI controller of varying parameters and nonlinear problems, proposed a fuzzy adaptive PI controller and then applied to speed cycle, PI controller parameters on-line self-regulation is achieved. The consequences of simulation indicated that the method modified the dynamic performance and obtained high robustness servo system simulation.
