三相交错并联Buck变换器的高阶滑模自抗扰控制
High-order Sliding Mode Active Disturbance Rejection Control for Three-phase Interleaved Parallel Buck Converter
摘要
Abstract
To address the issue of impact of multi-source disturbance on a three-phase interleaved parallel Buck convert-er,which further affect the current sharing effect and dynamic performance of the system,a high-order sliding mode ac-tive disturbance rejection inner and outer loop cascaded control strategy is put forward.First,the super-twisting sliding mode active disturbance rejection control is applied to the voltage outer loop.The disturbance information is introduced to the design of a super-twisting sliding mode controller,and the lumped disturbance of the system is assessed and com-pensated by an extended state observer.Second,to achieve the dynamic adjustment of the super-twisting sliding mode switching gain,an adaptive mechanism is incorporated into the current inner loop.Finally,the proposed cascaded con-trol strategy is designed using the Lyapunov stability theory to guarantee its stability.Experimental results confirm that compared with the conventional active disturbance rejection control,the proposed control strategy performs better in terms of robustness and dynamic responsiveness.关键词
