摘　　要：针对负载扰动造成永磁同步电机(PMSM)调速控制系统性能下降的现象,提出了基于新型趋近律的无模型滑模控制算法。搭建PMSM转速环超局部模型,利用新型趋近律来提高系统趋近阶段的收敛速度,并设计了一个改进无模型滑模控制器增强抑制扰动。通过与传统的PI控制的实验结果进行对比,验证了所提方法动态响应强,具有强抗扰能力。In order to solve the phenomenon that the performance of the permanent magnet synchronous motor(PMSM)speed control system is degraded due to load disturbance,a new model-free sliding mode control algorithm based on new reaching law is proposed.A superlocal model of the PMSM speed loop was constructed,and the new reaching law was used to improve the convergence speed of the system in the approach stage,and an improved model-free sliding mode controller was designed to enhance the suppression of disturbances.By comparing with the experimental results of traditional PI control,it is verified that the proposed method has strong dynamic response and strong anti-interference ability.
