WPT系统双边协同抗饱和控制策略研究
Dual-side Cooperative Control Strategy with Anti-windup Design for WPT Systems
摘要
Abstract
Under the dual-side cooperative control based on pulse density modulation,a wireless power transfer ( WPT ) system can maintain the power transmission at its maximum efficiency under changes in the coupling coefficient and load impedance.However,a current/voltage overshoot which far exceeds the rated value will occur during the system startup and battery constant-current and constant-voltage charging switching.To solve the problem of overshoot and ensure the battery charging stability,an anti-windup control strategy is proposed.First,the working principle of maximum efficiency point tracking is analyzed based on the equivalent circuit model of WPT system.Then,combined with the cooperative working process of control quantities on both sides of the WPT system,the overshoot phenomenon during the system startup and battery constant-current and constant-voltage charging switching is analyzed,and a design method for the constant-current and constant-voltage controller is given.The anti-windup control strategy is proposed by combining the anti-windup algorithm based on inverse calculation with the controller design.Finally,simulation results show that under the proposed anti-windup strategy,the overshoot caused by controller saturation can be effectively suppressed,the time for the system to reach its steady state decreases,and the component stress caused by current/voltage overshoot is also reduced.关键词
