永磁同步电机全局积分终端滑模矢量控制
Global Integral Terminal Sliding Mode Vector Control of Permanent Magnet Synchronous Motor
摘要
Abstract
To improve the speed control performance of a permanent magnet synchronous motor,a global integral termi-nal sliding mode vector control strategy based on ahigh-order logarithmic sliding mode disturbance observer is proposed.First,a reaching law whose reaching speed can be adjusted adaptively with the state variable is designed,and the sym-bolic function is replaced by a nonlinear function which can achieve a smooth transition at the zero point.At the same time,a global sliding mode factor is introduced into the improved integral terminal sliding mode surface,and a global integral terminal sliding mode speed controller is constructed to ensure that the control system has global robustness.Then,a logarithmic sliding mode surface which can realize convergence in finite time is combined with ahigh-order con-trol law to design the high-order logarithmic sliding mode disturbance observer.The observed system disturbance is used as a known quantity to compensate the front-end controller and improve the control accuracy.Simulation results show that the proposed strategy can significantly reduce speed fluctuations while improving the system stability.关键词
