Chattering free full-order terminal sliding-mode control for maximum power point tracking of photovoltaic cells

摘要: This study presents a new chattering free full-order terminal sliding-mode controller (FOTSMC) for maximum power point tracking of photovoltaic cells. The proposed system consists two loops, namely seeking loop and loop. utilises an adaptive perturb observe method (MPP) searching. Since the accuracy depends on loop, FOTSMC is used in MPP. control law continuous, therefore achieved. Furthermore, since derivatives terms with fractional powers do not exist law, singularity problem, which exists traditional controllers (TSMCs), avoided. Stability robustness presented. In order to evaluate results system, TSMC provided. Afterwards, performance verified through simulation experiment.
