针对一次侧控制的无线输电系统，提出了一种快速、鲁棒的控制策略。首先，通过分析与主功率变流器的所有可能配置相关的矢量场的特性，生成正弦参考轨迹信号。然后，根据变流器的开关行为和切换后的微分方程组的轨迹参考信号，设计了切换控制器，捕获了原边变流器的动态特性。最后，定义了参考轨迹周围的一组点来建立全局渐近稳定性。与其他控制器相比，该控制策略对负载的大变化和扰动具有更快的动态响应速度。仿真和实验结果表明，该方法有效地抑制了一次电流超调，提高了系统的响应性能。
This paper proposed a fast and robust control strategy for a wireless power transfer system using primary side control. First, a sinusoidal reference trajectory signal was generated by analyzing the properties of the vector fields associated with all possible configurations of the primary power converter. Then, a switching controller was designed based on the switching behavior of the converter and the trajectory reference signal for the switched differential equations, capturing the dynamics of the primary side converter. Finally, a set of points around the reference trajectory was defined to establish the global asymptotic stability. The proposed control strategy has higher dynamic responding speed to large variations and perturbations of the load in comparison to other suggested controllers. The simulation and experimental results show that the primary current overshoot was efficiently suppressed, and the system response performance was improved.
