摘　　要：文章针对永磁同步电机(PMSM)复杂、强耦合的非线性特点,克服传统PI控制算法控制精度不高、响应速度慢等特点,研究了一种基于时间尺度参数整定的改进型自抗扰控制(ADRC)PMSM控制策略。在改进的ADRC的基础上从时间尺度概念入手分析参数整定问题,通过理论分析得出PMSM的时间尺度,结合时间尺度与ADRC参数的关系进行参数整定。仿真结果表明,该方法在ADRC控制下有良好的动态性能同时对不同的PMSM均具有良好的鲁棒性和抗干扰能力。Aiming at the characteristics of complication, strong coupling and nonlinear of permanent magnet synchronous motor （PMSM） and the low accuracy slow response characteristics of traditional PI control algorithm, an imprved ADRC PMSM algorithm control strategy based on time scale is researched in this paper. Parameter tuning problem is analysed on the basis of improved ADRC from time scale conception. Time scale of PMSM is obtained by theoretical analysis. Combined with time scale and the relationship ofADRC paraneters, the parameter tuning is carried on. The simulation results show that the method under the control of the ADRC has good dynamic performance, for different PMSM meanwhile, it has good robustness and anti- disturbance capabilities.
