为了实现对永磁同步电机很好控制的目的，采用反馈线性化的方法，通过求取输出变量的李导数，得到需要的坐标变换和状态反馈变量，设计了控制器。利用MatLab7.6/Simulink做了基于SVPWM的永磁同步电机的反馈线性化控制仿真实验。在加不同大小负载的情况下，验证算法对不同负载速度跟踪的效果，获得了反馈线性化控制对永磁同步电机跟踪控制效果好的结果，得到了反馈线性化控制具有很好的鲁棒稳定性，是控制非线性系统的一个好方法结论。% The feedback linearization method was used to control the permanent magnet synchronous motor(PMSM)per⁃fectly. Through calculating the output variables of the Lie derivative,the needed coordinate transformation and state feedback variables were obtained,and then the controller was designed. With the Matlab7.6 / Simulink,a simulation experiment was done for feedback linearization control of PMSM based on SVPWM. Under the conditions of different loads,the speed tracking effect of the algorithm was verified. A conclusion,that the feedback linearization control is good for tracking control of PMSM and has robust stability,was got.
