永磁同步电机滑膜变结构MATLAB仿真

摘要

针对多变量,非线性,强耦合的永磁同步电机(PMSM)系统设计了一种转速控制器,利用滑模控制的鲁棒性强,可以弥补传统PI控制鲁棒性弱的缺点,设计了滑模转速控制器.首先介绍了PMSM矢量控制下的坐标变换,然后建立了转速滑模控制器,并证明了稳定性,其次介绍了SVPWM的步骤,最后以MATLAB进行了仿真验证,结果表明所设计控制器较传统控制抑制抖振效果佳,控制性能好.%For multi-variable,nonlinear,strong coupling of Permanent Magnet Synchronous Motor (PMSM),a speed controller system design,the use of robust sliding mode control is strong,it can make up for the traditional PI control robustness weak shortcomings design sliding speed controller!introduces the coordinate transformation under PMSM vector control,and the establishment of a sliding mode speed controller,and prove the stability,followed by the introduction SVPWM steps were finally MATLAB simulation results show that the controller design than traditional control suppressing buffeting good effect,good control performance.
