| 摘 要： | 针对传统控制策略不能将永磁同步电机（PMSM）完全解耦的问题，介绍了一种以反馈线性化解耦为基础的新型滑模控制方法。首先运用微分运算和反馈线性化原理,把PMSM控制系统划分成两个相互独立的线性子系统，即转速子系统和电流子系统。其次考虑到系统鲁棒性差的问题，提出加入终端吸引子模型的新型滑模控制器。最后仿真结果表明，采用上述两种方法相结合的控制策略，可以提升系统控制精度、快速性和鲁棒性。

| Abstract: | A new sliding mode control method based on feedback linearization decoupling is introduced to solve the problem that the traditional control strategy cannot completely decouple permanent magnet synchronous motor (PMSM). Firstly, the PMSM control system is divided into two independent linear subsystems, namely the speed subsystem and the current subsystem, by using differential operation and feedback linearization principle. Secondly, considering the poor robustness of the system, a new sliding mode controller with terminal attractor model is proposed. Finally, the simulation results show that the control strategy combined with the above two methods can improve the control precision, rapidity and robustness of the system. |
