摘要
Abstract
A control strategy of three-phase PWM rectifier based on direct power control was proposed which used fractional-order PID controller.Double control-loop was designed based on instantaneous power theory,and the inner-loop is power control-loop,the external-loop is voltage control-loop.Fractional-order PID controller was used to control the DC voltage,because the integer-order PI controller has poor anti-interference performance and plays sensitive to the parameter-varying of the system.The fractional-order PID controller was designed by frequency domain design method under the power model of the system.The simulation results show that the fractional-order PID controller has good dynamic performance,robust performance,quick response,and accurate control results,better than PI controller.关键词
