Abstract

Aiming at the problem of thrust fluctuation during the operation of the electromagnetic pump, a new composite control method is proposed in the control strategy of the inverter power supply. The method adopts a strategy combining repetitive controller and QPR controller. Repetitive controller has a good inhibitory effect on periodic disturbances, and can also improve the output accuracy of the inverter power supply. QPR controller improves the dynamic characteristics of the power system. While ensuring the stability of the system, the output precision of the inverter power supply is improved, which helps to improve the working efficiency of the electromagnetic pump.
