摘　　要：结合PMSM的矢量控制技术,简要分析了SVPWM的算法,并介绍了MATLAB下建立其仿真模型的方法。讲述了滑模变结构控制的原理,提出了用于PMSM速度控制的滑模控制调节器,并给出了详细的设计方法。建立了系统的仿真模型,仿真结果表明,采用滑模变结构控制器使系统具有较快响应速度、较好的抗干扰能力和鲁棒性。Combining with PMSM vector control technique, this paper analyzes the algorithm of SVPWM briefly, and introduces the methods how to construct this model under MATLAB. Based on the discussion of sliding mode Control theory, the paper also proposes a speed regulator used SMC for the PMSM, then the design method is introduced in detail. Finally, the model of the system is established, the result of simulation shows that to use the SMC speed regulator can make the control system has the advantages of rapid response, strong anti - disturbance and robustness.
