摘　　要：传统的无刷直流电机(Brushless DC Motor,BLDCM)的控制方式通常采用转速PI控制,转速电流PI控制等控制策略,这类控制方法简单,但同时也存在一些转速误差较大,转矩抖动明显等问题.为解决这些问题,采用矢量控制策略,并提出积分滑模算法(Sliding Mode Control,SMC)代替电流q轴分量PI调节算法.通过搭建该调速系统仿真模型及实验分析,与传统PI控制算法相比,该系统转速跟踪误差小,转矩抖动明显减小,系统动态响应快,鲁棒性强.The control method of Brushless DC Motor （BLDCM） usually adopts the control strategy of speed PI control and speed current PI control. Such control method is simple, but there are some problems such as large error of rotational speed, obvious torque jitter and other issues. To tackle these problems, vector control strategy is used and an integral sliding-mode control algorithm（ SMC ） is proposed to replace the current PI control algorithm. Compared with the traditional PI control algorithm, this system has small speed error and small torque jitter. The dynamic response of the system is fast and the robustness is strong.
