摘　　要：针对永磁同步电机空间矢量直接转矩控制中存在的磁链脉动大、转速超调大和转速动态响应速度慢等问题,提出基于Super-twisting二阶滑模控制理论将转速环、磁链环和转矩上的控制器全部换成Supertwisting滑模控制器。对所提出的控制理论利用MATLAB/Simulink仿真软件进行仿真验证。仿真结果表明所提出的控制理论能够成功抑制转速超调,实现提高转速、磁链和转矩的动态响应速度、抑制转矩和磁链脉动。To solve the problem of the flux ripple,big speed overshoot and slow dynamic response speed in the space vector direct torque control of permanent magnet synchronous motor,the controller of speed loop was replaced,speed loop and torque loop with Super-twisting slide mode controller based on the theory Super-twisting slide mode.The proposed control theory was simulated and verified by the software of MATLAB/Simulink simulation. The simulation results showed that the proposed control theory could successfully suppress the overshoot of speed,improve the dynamic response speed,flux and torque,and restrain the torque and flux ripple.
