摘　　要：由于逆变器非线性及绕组非对称性,双三相同步电机驱动系统含有大量周期扰动。其以谐波电流的形式存在于定子绕组中,引起电流失真及系统损耗。针对该问题,提出基于比例谐振扩张状态观测器的谐波抑制方法。叠加比例谐振模块的扩张状态观测器除观测总扰动外,旨在放大谐波电流幅值;针对改善后的被控对象,引入模型预测电流控制提升系统动态响应特性。实验结果表明该方法可有效降低系统损耗,提升电流正弦度。Due to the nonlinearity of inverter and winding asymmetry,the dual three-phase synchronous motor drive systems contain a large number of periodic disturbances.They exist in the stator winding in the form of current harmonics,which causes current distortion and system loss.A harmonic suppression method based on proportional resonance-extended state observer is proposed to address the problem.Firstly,the extended state observer superimposed with multiple proportional resonant modules not only observes the total disturbance of the harmonic subspace,but also aims to amplify the harmonic current amplitude.Secondly,as for the controlled objects after the improvement,the model predictive current control is introduced to improve the dynamic response of the system.Finally,the experimental results show that the proposed method can effectively reduce the system loss and improve the current sine degree.
