摘要
针对内置式永磁同步电机电流与转速的非线性耦合及系统参数变化鲁棒性变差问题,提出基于状态反馈线性化解耦滑模变结构新型控制策略。通过非线性状态反馈和坐标变换,实现了内置式永磁同步电机系统线性化解耦控制,将原系统分解为2个线性子系统:转速线性子系统和励磁电流线性子系统。基于滑模变结构理论,对2个子系统分别设计滑模变结构控制器,整个系统结构简单,易于实现。实验结果表明,基于状态反馈线性化解耦滑模变结构控制的内置式永磁同步电机系统具有较好的动态性能和对参数变化良好的鲁棒性。
Because of the nonlinear coupling of current and speed in the interior permanent magnet synchronous motor （IPMSM） system, and the had robustness while the system parameters variation, the new control strategy of linearization sliding mode control for the IPMSM was proposed. By nonlinear state feedback and coordinate transformation, the decoupling control strategy comes true for the IPMSM system, and the original system is decomposed into two linear subsystems： a speed linear subsystem and the excitation current linear subsystem. Based on sliding mode theory,the sliding mode controller were designed for the two subsystems, and the whole system is very simple and easy to implement. Experiment results show that, based on the state feedback linearization sliding mode deeoupling control system for the IPMSM has good dynamic performance and robustness while the parameter changes.
