摘要
双绕组永磁同步电机通过绕组串、并联重构能有效提升系统的运行范围。然而绕组不同模式下的参数变化造成传统PI控制器无法满足系统高品质运行要求。该文针对此类电机的运行特点,研究了一种集转速环控制和抗扰观测的复合滑模变结构控制器,有效抑制了电机参数变化及绕组重构引起的转速动态波动问题。首先,分析了双绕组永磁同步电机不同模式下的工作机理、绕组重构时转速波动产生的原因。其次,设计了滑模变结构控制器以实现控制参数的自适应,快速满足重构瞬间电流关系以抑制动态波动。最后,利用小型原理样机,对采用PI控制器和滑模变结构控制器方案进行了典型工况下的对比实验,验证了所提控制策略的有效性和可行性。
Dual-winding permanent magnet synchronous motor(PMSM)can improve the operating range by reconfiguring the windings of the series and parallel modes.However,the motor parameters variation in different winding modes could cause the traditional PI controller to be unable to satisfy the high-quality operation requirements.According to the operating characteristics of this type of motor,this paper studies a composite sliding mode variable structure controller that integrates speed loop control and anti-disturbance observation,which could effectively suppress the dynamic fluctuation of speed caused by motor parameter variation and winding reconstruction.Firstly,the working mechanism of the dual-winding PMSM in different modes and the reasons for the speed fluctuation during winding reconstruction are analyzed.Secondly,a sliding mode variable structure controller is designed to realize the self-adaptation of control parameters and quickly meet the reconstruction of the instantaneous current relationship to suppress dynamic fluctuations.Finally,a comparative experiment is carried out under typical working conditions for the scheme using PI controller and the sliding mode variable structure controller through a miniature principle prototype,which verifies the effectiveness and feasibility of the proposed control strategies.
