The periodic force disturbance is generated by specially existing end effect of PMLSM, which can not be rejected effectively by the disturbance observer. For that a repetitive controller is designed in the position loop to restrain the periodic disturbances.
针对PMLSM存在特有的端部效应而引起附加的周期性推力扰动,在扰动观测器已削弱了这种周期扰动的基础上,有针对性地提出在位置回路中增设一个重复控制器来抑制这种周期性扰动,解决端部效应所引起的推力周期性波动问题。
