摘要
CLC谐振型感应电能传输系统较传统的LC谐振型系统具有更大的谐振容量和更小的频率漂移,但由于系统的高阶及多周期点特性,对CLC型系统的控制更为困难。为实现CLC谐振型系统的输出鲁棒控制,将系统状态变量及非线性开关函数进行频域线性化,通过平衡点变换,得到平衡点附近的广义状态空间平均(generalized state space averaging,GSSA)扰动模型。建立了系统的H∞控制系统结构,提出GSSA模型误差扰动有界定理并给出了证明。给出了相应的H∞扰动控制律,并通过仿真及实验结果验证了该模型及控制方法的有效性。
Compared with LC resonant inductive power transfer （IPT） System,CLC resonant IPT system is characterized by more resonant capacity and less frequency drift.Attributed to system multi-frequency operating points and high order characteristics,the control of CLC resonant IPT system is difficult to realize.In order to realize robust control,the paper expanded system state variables in frequency domain and get the linearization model of system switch function.With equilibrium points transform,the paper presented system generalized state space averaging （GSSA） disturbance model and put forwards system H∞ control system structure.Furthermore,the paper presented GSSA disturbance model error bound theorem and its proof.The H∞ control theorem was also presented as well.Simulation and experiment results verify the H∞ control method for CLC resonant IPT system.
