摘要
针对感应电能传输系统的输出控制,利用原边逆变电路的能量注入模式及自由谐振模式,提出一种基于双工作模式切换的能量注入调节方法。该方法建立了谐振网络能量函数以刻画系统中能量平衡关系,并以能量注入、能量储存及能量耗散三者关系,提出了基于能量注入占空比的系统控制策略。该控制方法从能量角度实现控制,有效地避免了该非线性系统的复杂建模及控制设计过程,实验结果验证了该方法的有效性。
Aimed at output control of inductive power transfer systems,a novel energy injection adjusting strategy is presented.The output adjusting strategy is realized by switching between energy injection mode and free resonance mode.Furthermore,the energy equilibrium relationships of each switching mode in resonant network are presented.The output control is realized by duty cycle control of energy injection according to the relationships among energy injection,storage,and dissipation.The controller is designed and realized on the basis of energy analysis to avoid complex nonlinear system modeling.Finally,experiment results verify the energy injection adjusting strategy and the controller design method.
