摘　　要：针对永磁同步电机模型参数扰动的问题,提出了一种基于扰动观测器的永磁同步电机复合非奇异终端滑模驱动控制策略。新型控制器在传统矢量控制的基础上结合使用了扰动观测器和非奇异终端滑模控制器,是一种复合控制策略。同时新的控制策略引入了扰动观测器进行前馈补偿,以减小控制器增益。最后搭建了永磁电机驱动控制试验平台开展了对比试验研究,试验结果验证了新型控制策略的优势。Aiming at the problem of the time-varying parameters and disturbances for a permanent magnet synchronous motor drive system,a composite nonsingular terminal sliding mode control scheme for the permanent magnet synchronous motor drive system was introduced. Based on the traditional vector control,the new controller combined the disturbance observer and the nonsingular terminal sliding mode controller,so it was a composite control strategy. And the new controller introduced disturbance observer as feedforward controller. Finally,the comparative experiment was carried out on the permanent magnet motor drive control test platform. The experimental results verify the advantages of the new control strategy.
