摘要
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.
