摘　　要：针对表贴式永磁同步电机矢量控制调速系统容易受到负载扰动等不确定性因素影响的问题,提出了一种基于扩张状态观测器的永磁同步电机无模型自适应滑模控制方法。首先对传统永磁同步电机的转速和电流数学模型进行分析处理,归纳出系统对应的超局部模型;然后根据系统超局部模型设计出无模型的自适应滑模速度控制器和电流控制器,通过自适应切换增益来减少系统中的抖振现象,并利用扩张状态观测器对转速环和电流环中的总和扰动及未建模量F估计并进行前馈补偿;最后通过仿真和半实物实验平台验证了所提控制方法的可行性与有效性。In the view of the problem that surface permanent magnet synchronous motor(SPMSM) is susceptible to load disturbance and other uncertain factors, a model-free adaptive sliding mode control strategy based on the extended state observer(ESO) is proposed in this paper. Firstly, the traditional speed and current mathematical models of permanent magnet synchronous motor(PMSM) are analyzed and the ultra-local model of SPMSM is concluded. Then, the adaptive sliding mode controllers of speed and current are designed according to the ultra-local model of SPMSM. They can reduce the chattering phenomenon by the adaptive switching gain and the second order extended states observers in the loops of speed and current can compensate the summation perturbation and the variable F without modeling. Finally, the results of the simulation and experiment verify the effectiveness and practicability of the proposed control strategy as described above.
