The invention aims to provide a control method for a bidirectional DC-DC converter optimized by applying a genetic algorithm, and the method comprises the following steps: S1, establishing an adaptiveobserver of a buck converter, and establishing an observer for total interference; S2, establishing a finite-state machine controller based on adaptive nonsingular fast terminal sliding mode controlfor the buck converter in the step S1, and obtaining a finite-state machine controller convergence condition based on adaptive nonsingular fast terminal sliding mode control; and S3, optimizing the adaptive fast terminal sliding mode controller in the step S2 through a genetic algorithm. According to the method, the genetic algorithm is adopted to perform parameter optimization on the adaptive fast terminal sliding mode controller in the control strategy, so that the DC-DC converter has a better power control effect.

    本发明的目的是提供一种运用遗传算法优化的双向DC‑DC变换器的控制方法,包括以下步骤:S1,建立buck变换器的自适应观测器,对总干扰建立观测器;S2,针对S1步骤所述的buck变换器建立基于自适应非奇异快速终端滑模控制的有限状态机控制器,并获得基于自适应非奇异快速终端滑模控制的有限状态机控制器收敛条件;S3,对S2步骤所述的自适应快速终端滑膜控制器通过遗传算法进行优化。本发明采用遗传算法对控制策略中的自适应快速终端滑膜控制器进行了参数优化,使得DC‑DC变换器对功率控制的效果更好。
