Adaptive Sliding-Mode Controller for Flyback-Based PV Systems Featuring Constant Switching Frequency

This paper proposes a sliding-mode controller to ensure both the global stability and maximum power generation of photovoltaic system based on flyback converter. The is an adaptive sliding-surface, which designed impose constant frequency switching converter, thus simplifying selection passive active elements device. Moreover, analyzed using transversality, reachability equivalent control conditions. solution also includes auto-tuning process for parameters perturb observe algorithm, are calculated controller, ensuring PV stability. Finally, performance complete verified detailed circuital simulations realistic application case.
