摘要
本文针对传统PI控制策略的PMSM矢量控制系统存在启动转矩、转速波动大,动态性能不够理想等问题,提出了模糊-PI双模控制策略,并设计了模糊-PI控制器。在Matlab/Simulink仿真平台下建立了控制器模型并给出了仿真结果,通过与传统PI控制策略的仿真结果相比较,可以看出,这种新型的模糊-PI双模控制策略显著提高了系统的响应速度,改善了系统的动态性能。
The PMSM vector control of the traditional PI control scheme has problems that the pull-in torque is strong,the fluctuation of the rotating speed is heavy,the dynamic characteristics are not ideal,etc.So in this paper,a kind of two dimensional Fuzzy-PI control scheme was contrived and the controller was designed.they build the model of controller and get the simulation results,which based on the Matlab/Simulink environment,compared with the traditional PI control scheme,they find that this new control scheme of two dimensional Fuzzy-PI heighten response speed and improve dynamic performance of the system obviously.
