内置式永磁电机状态反馈线性化解耦滑模控制
Sliding Mode Control for Interior Permanent Magnet Synchronous Motor Based on State Feedback Linearization
摘要
Abstract
Because of the nonlinear coupling of current and speed in the interior permanent magnet synchronous motor (IPMSM) system,and the bad 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 decoupling control system for the IPMSM has good dynamic performance and robustness while the parameter changes.关键词
