摘　　要：为了提升永磁同步电机(PMSM)转速控制性能,设计了一种用于PMSM的两自由度(TDOF)鲁棒转速控制器。控制器中电流内环沿用了传统PI调节器,而转速调节使用了TDOF控制。在考虑了PMSM数学模型中非线性因素的基础上完成了闭环系统的全局指数稳定性证明,所得到的稳定条件可作为参数整定依据。TDOF鲁棒转速控制器对表贴式和内嵌式PMSM均适用,并对参数不确定性和外部转矩扰动具有非常好的鲁棒性。利用PMSM驱动测试平台开展了TDOF鲁棒转速控制器与传统PI转速控制器的对比实验,实验结果显示出新方案在控制性能和调试简便性等方面具有显著优势。In order to improve the performance of permanent magnet synchronous motor(PMSM)speed control,a two-degrees-of-freedom(TDOF)robust speed controller for PMSM was designed. The traditional PI regulator was used as the current inner loop in the controller,while TDOF controller was used for speed adjustment. The proof of the global exponential stability of the closed-loop system was completed based on considering the nonlinear factors in PMSM mathematical model,and the obtained stability conditions could be used as the basis for parameter tuning.TDOF robust speed controller is suitable for both surface-mounted and interior PMSM,and has very good robustness to parameter uncertainties and external torque disturbances. Based on the PMSM driving test platform,the comparison experiments between TDOF robust speed controller and traditional PI speed controller were carried out.And the experimental results show that the new scheme has significant advantages in terms of control performance and ease of debugging.
