WPT系统线性自抗扰复合控制策略
A Hybrid Control Method with Linear Active Disturbance Rejection for WPT System
摘要
Abstract
In view of the problems of unstable power transmission and low efficiency of the wireless power trans-mission system when it is affected by external interference,this study proposes a composite control method for wireless power transmission with high efficiency and high stability based on linear active disturbance rejection control.The ef-fective values of the voltage and current at the input end of the wireless power transmission system are sampled to i-dentify the coupling coefficient.The impedance matching is carried out by adjusting the duty cycle of the Buck-Boost circuit on the output side to achieve maximum efficiency tracking.The linear active disturbance rejection control is a-dopted to adjust the phase shift angle of the full-bridge inverter on the input side to ensure the stable and efficient power transmission of the system.The proposed method realizes the decoupled operation between the two control loops of high-efficiency power transmission and constant voltage output of the wireless power transmission system.The simu-lation results show that the system can stably transmit power when affected by external interference,and the system transmission efficiency is maintained above 90%.Compared with the proportional-integral control,the linear active disturbance rejection control has a better dynamic regulation effect on the output voltage when facing load disturbances and reference voltage disturbances.关键词
