摘　　要：为了控制伺服内置式永磁同步电机(IPMSM)驱动,提出一种基于微分平滑度方法的非线性控制算法,利用其电压降来计算负载转矩干扰和定子电阻,提出了IPMSM驱动结构的动力学和稳定性问题的简单解决方案,并且在实验室中设计了硬件系统,基于dSPACE控制器DS1104平台获得数字估计,同时使用1 000 W和3 000 rpm的小型电机进行仿真和实验研究,分析结果显示该控制方案在电机驱动循环过程中出色的控制性能.To control the servo interior permanent magnet synchronous motor(IPMSM) drive, a nonlinear control algorithm based on differential smoothness method is proposed. The voltage drop is used to calculate load torque disturbance and stator resistance. A simple solution to the dynamics and stability problems of the IPMSM drive structure is proposed. And in the laboratory to achieve the hardware system,using the d SPACE controller DS1104 platform to obtain digital estimates. Simulations and experimental studies were performed using small motors of 1000 W and 3000 rpm. The results show that this control scheme demonstrates the excellent control scheme performance during the motor-driven cycle.
