文章采用一种新型高阶滑模控制技术以及滑模微分器实现永磁同步电机位置跟踪控制,提出了电机磁通、电阻的辨识方法。由于系统输出耦合,文中首先利用反馈线性化进行解耦,并设计了高阶滑模控制器。考虑到定子电阻和永磁体磁链是随温度变化而变化的,文章介绍了一种新型参数估计方法,通过对同步电机高阶滑模控制器设计,并结合一个精确滑模微分器来实现电机内部参数的辨识,减小参数扰动对控制性能的影响。仿真实验的结果表明,多输入多输出的永磁同步电机磁通、电阻得到了估计,系统具有较好的动态性能。

＜正＞This paper mainly deals with a high order sliding mode controller for nonlinear permanent magnet synchronous motor（PMSM）.This kind of approach eliminates the chattering phenomenon *** combining precious feedback linearization and sliding mode control,it is very suitable for parameters uncertainties of PMSM since the environment *** simulation results indicate that effect of synchronous motor position servo tracking is good,and chattering problem is avoided.
