摘　　要：为了提高永磁同步电机的鲁棒性和跟踪精度,提出一种新型固定时间终端滑模控制方法.首先,在d-q坐标系中构建永磁同步电机的数学模型,给出q轴电流和电机转速的表达式;其次,通过给出的固定时间终端滑模的滑模面和导出的系统控制输入表达式,实现电机转速的固定时间收敛.仿真结果表明,相比于传统比例积分和滑模算法,所提控制方案可有效改善永磁同步电机的响应速度、运行稳定性和抗干扰性能.In order to improve the robustness and tracking accuracy of permanent magnet synchro-nous motor(PMSM),a novel fixed-time terminal sliding mode(TSM)control method is proposed.Firstly,the mathematical model of PMSM is constructed in d-q coordinate system.Then,the slid-ing mode surface design of fixed-time TSM is given and the control input of the system is derived.The advantage of this control scheme is that the convergence time for the motor can be set in advance without considering its initial state.Simulation and experimental results show that com-pared with traditional proportional integral(PI)and sliding mode control algorithms,the proposed control scheme can effectively improve the response speed,operation stability and anti-interference of the motor.
