摘　　要：由于在转子磁场定向矢量控制中,转速PI控制器抗干扰能力较差,提出了采用模糊免疫PID控制器取代转速PI控制器,对提高异步电机控制系统的性能起到改善作用。模糊免疫PID控制将生物免疫机理、模糊控制理论及PID控制理论相结合,提高了系统的自适应能力,实现了控制器参数的优化及在线自整定。构建了基于模糊免疫PID控制器和空间矢量脉宽调制的异步电机矢量控制系统。仿真结果表明,该系统既具有良好的动、静态特性,也具有自适应和鲁棒性强的特点。Because the less anti-interference performance for the speed PI controller in the rotor flux field oriented vector control system, it was presented that fuzzy immune PID controller substitutes the speed PI controller, which improved the performance of asynchronous motor vector control system. A fuzzy immune PID control algorithm which combined biological immune mechanism, fuzzy control theory and PID control theory enhanced the self-adaptability of fuzzy immune PID controller and realized parameter optimization and self-tuning on line for fuzzy immune PID controller. Furthermore, the asynchronous motor vector control system based on the fuzzy immune PID controller and space vector pulse width modulation was structured. Results of simulation showed that the system not only has good static and dynamic performance but also has strong self-adaptability and robustness.
