具有变指数系数的DC/DC变换器鲁棒固定时间滑模控制

In this article, a novel disturbance observer-based sliding mode control scheme with fixed-time convergence mechanism is proposed to regulate the output voltage of dc–dc buck converters. First, to assure that the convergence time of the voltage tracking process is independent of the initial state, a new varying exponential coefficient fixed-time sliding mode controller (VECFxTSMC) is proposed in t...
