摘　　要：为了提高永磁同步电机调速系统的性能,提出一种基于扩张状态观测器的分数阶滑模预测转矩控制策略。采用扩张状态观测器对电机的综合扰动项、定子电流和反电动势进行实时观测,可快速准确得到它们的估计值并进行补偿;利用估计值构建分数阶滑模控制器来削弱系统抖振并提高鲁棒性;利用转矩和磁链无差拍预测控制,减少了遍历次数并降低了计算复杂度。通过仿真和半实物平台进行了验证,所得结果表明,所提出的方法能有效提升系统的鲁棒性,使电机具有良好的动态和静态性能。In order to improve the performance of PMSM speed control system,a fractional sliding mode predictive torque control strategy based on extended observer is proposed.The comprehensive disturbance term,stator current and counter electromotive force are observed in real time by using the extended observer,and their estimates can be quickly and accurately obtained and compensated.Building a fractional-order sliding mode controller with estimates to reduce system chattering and improve robustness.Deadbeat predictive control for torque and flux linkage reduces traversal times and computational complexity.Validated through simulation and hardware-in-the-loop platforms,the results obtained show that the proposed method can effectively improve the robustness of the system and make the motor have good dynamic and static performance.
