Passive Backstepping Sliding Mode Control Strategy for Photovoltaic Grid-connection Based on MMC
摘要
Abstract
To address the issues of weak disturbance rejection,poor harmonic suppression capability,and slow response speed in photovoltaic(PV)grid-connected systems under traditional control methods,a passive backstepping sliding mode control strategy based on a modular multilevel converter(MMC)is proposed.First,according to the mathematical model of the MMC and the theory of passive control,the positive-and negative-sequence passive controllers are designed to enhance system stability.Then,sliding mode control is integrated to improve system robustness,and backstepping control is further introduced to optimize dynamic performance.The proposed passive backstepping sliding mode control strategy enables the coordinated operation of passive control,backstepping control,and sliding mode control.Finally,simulations are carried out on the MATLAB/Simulink platform,and the proposed method is compared with passive sliding mode control,conventional sliding mode control,and PI control.The simulation results show that the coordinated control of the three methods significantly enhances the system's disturbance rejection and harmonic suppression capabilities,while also accelerating its dynamic response.Compared with other control strategies,the proposed passive backstepping sliding mode control demonstrates superior stability,stronger robustness,and faster response speed.关键词
