摘　　要：采用Filippov方法对双向DC-DC变换器在状态反馈控制下的动力学特性进行详细分析。建立双向DC-DC变换器的状态反馈控制模型并采用Filippov方法推导系统的单值矩阵,应用Floquet理论采用数值仿真分析系统的动力学特性并与峰值电流反馈进行对比分析,仿真和实验的结果验证了理论分析的正确性。In this paper,the Filippov method is used to analyze the dynamic characteristics of bidirectional DC-DC converter under state feedback control.The state feedback control model of the bidirectional DC-DC converter is established and the monodromy matrix of the system is derived using the Filippov method.The numerical simulations and Floquet theory are used to analyze the dynamic characteristics of the system and the results are compared with the system under the peak current feedback.Simulation and experimental results verify the correctness of the theoretical analysis.
