摘要: 为了改善移相全桥直流变换器的输出性能,提出一种重积分间接滑模控制策略.给出了移相全桥的动态模型,同时采用李导数给出重积分间接滑模控制器的设计过程.分析了间接滑模控制过程中的降阶现象;在三维相空间中描述了滑模存在域和滑动过程,并给出滑模系数的整定公式.仿真和实验结果表明,该控制策略可提升移相全桥变换器的鲁棒性和动态品质,在保留滑模控制优点的同时有效消除间接滑模控制导致的输出残差.

Abstract: A double integral indirect sliding mode control strategy was proposed for phase-shifted full-bridge (PSFB) DC-DC converters to improve the output performance. The theoretical analysis of motion of sliding mode controlled system was done according to Lie derivative method. The order reduction in the process of indirect sliding mode controlling was analyzed. The existence region of sliding mode and sliding motion were described in three-dimensional phase space. The selection basis of the sliding surface coefficients was given. Experimental results show that the proposed control strategy can improve the robustness and dynamic quality of PSFB, and eliminate state errors in the output, based on the fortes of sliding mode control.

Key words: phase-shifted full-bridge, indirect sliding mode control, double integral sliding mode control, robustness, Lie derivative
