摘要
提出一种基于双积分滑模控制的双向有源全桥(DAB)DC-DC变换器电压控制策略,该策略在模型精度要求低、控制器设计流程简单的情况下,可以获得良好的控制效果。首先,基于单移相调制方式建立变换器的降阶模型。然后,采用双积分滑模控制理论设计变换器的输出电压控制器。设计过程通过引入时域分析法进行滑模面系数的选取分析。最后,仿真和实验结果表明了所提控制策略的有效性。
A dual active bridge(DAB)DC-DC converter voltage control strategy based on double-integral sliding mode control was proposed,which can obtain good control effect under the condition that the model accuracy requirements are low and the controller design process is simple.Firstly,the reduced-order model of the converter was established based on the single-phase shift modulation mode.Then,the output voltage controller of the converter was designed by using the double-integral sliding mode control theory.The design process introduced the time domain analysis method to analyze the sliding surface coefficients.Finally,simulation and experimental results show the effectiveness of the proposed control strategy.
