双三相永磁同步电机电流谐波抑制的扩张状态观测器优化策略
Improved Extended State Observer for Current Harmonic Compensation in Dual Three-phase PMSMs
摘要
Abstract
Dual three-phase permanent magnet synchronous motors suffer from significant stator current harmonics due to inverter nonlinearity,non-sinusoidal back-electromotive force,and external disturbances.Although the conventional extended state observer with resonant terms can effectively observe periodic disturbances,other frequency disturbances suppression performance will be reduced.To address this issue,an optimization method for extended state observer is proposed.First,two disturbance dynamics models are established,based on which conventional resonant extended state observers(ESOs)are systematically classified and modeled.Then,the observer structure is optimized with a notch filter.An effective parameter configuration is proposed to reduce interference among observations of different frequency disturbances and ensure robust suppression over a wide speed range.Additionally,the proposed method can flexibly tune the suppression frequency ranges and strength for periodic disturbances,leading to better performance.Frequency-domain analysis is used to compare the performance of different observers for various frequency disturbance at different speed.Finally,the proposed method is validated on a dual three-phase motor experimental platform.Experimental results show that the proposed method can improve the accuracy of harmonic observation and has good current noise suppression capability.关键词
