摘　　要：为了抑制直流偏置型正弦电流电机中的谐波电流,同时保证电机的动态性能,研究了一种谐波电流抑制技术。在多旋转坐标系中对各次谐波电流进行闭环电流调节,使得这些谐波电流可以在稳态和动态过程中被有效地抑制,该控制策略不受电机饱和效应的影响。通过台架实验验证了该策略的有效性。In order to suppress the harmonic currents in DC-biased sinusoidal current machines,and guarantee the dynamic performance of the motor at the same time,a harmonic current suppression technology was studied.Through the closed loop current regulation of each harmonic current in multiple synchronous rotating reference frames,the harmonic currents can be effectively suppressed in steady state and dynamic performances.Furthermore,the method is not sensitive to motor's saturation.The effectiveness of the optimal current control strategy was validated by experimental results of a prototype machine.
