为了研究混合励磁双凸极电动机(HEDS)调速系统性能,给出了HEDS的数学模型及控制策略。采用S imu link/PSB工具箱,建立了HEDS电动机及其系统的一体化仿真模型。根据该类电机的驱动控制策略和方案,进行了不同运行条件下的仿真。结果表明,与DSPM电动机相比,HEDS电动机低速时具有更高的输出转矩,高速时有更宽广的调速范围,且其动态响应速度更快。
To research the performance of hybrid excited doubly salient motor (HEDS) control system, a HEDS mathematical model and the control strategy were given. Simulation control system was built by Simulink/PSB. According to control strategies , several simulations under different situations are designed. The results show that in comparison with DSPM, HEDS has higher torque at low speed,wider speed range at high speed, and better dynamic response.
