Simplified Super-Twisting Sliding Mode Applied to Dc-Bus Voltage Regulator
摘要
To perform the dc-link voltage stability and its robustness of a photovoltaic (PV) grid- connected system, simplified super twisting sliding mode (SSTC) strategy is presented in this work. Where the tracking superiority of the SSTC control is clearful in dc-link bus voltage regulation with fast transient response, low oscillations and the reducing of current total Harmonic Distortion (THD) under any weather conditions;to show the superiority of the between the proposed controller(SSTC) comprehensive comparisons are done with the conventional Proportional–Integral (PI), using MATLAB/SIMULINK.
