Attributed to system multi-frequency operating points and 零电压开关(zero voltage switching，ZVS)工作频率 high order characteristics, the control of CLC resonant IPT system is difficult to realize. In order to realize robust control, 漂移及原边激磁电流下降[1-6]，导致功率传输能力及 the paper expanded system state variables in frequency domain 整体效率下降。在频率漂移超过一定范围后，系统 and get the linearization model of system switch function. With 甚至会出现多周期工作点工作现象[7-9]，影响系统运 equilibrium points transform, the paper presented system 行稳定性。 generalized state space averaging (GSSA) disturbance model 针对单级 LC 谐振的诸多问题，文献[10]提出 and put forwards system H∞ control system structure. Furthermore, the paper presented GSSA disturbance model 基于 CLC 复合谐振的非接触电能传输系统。该系 error bound theorem and its proof. The H∞control theorem was 统将 LC 谐振与π型谐振网络结合，形成复合谐振。 also presented as we
