Robustly stabilizing min-type control for a multi-input DC-DC converter with output load estimation
Résumé
We propose a robustly stabilizing min-type control scheme for a Multi-Input Converter (MIC) using a Nonlinear Disturbance Observer (NDO) for the load current estimation. The closed-loop system ensures an output voltage regulation and eliminates the requirement of knowing the current load, thus mitigating the impact of current fluctuations, without relying on typically inaccessible or impractical measurements. Robust asymptotic stability is guaranteed by Lyapunov theory. The main result is validated by simulations and experiments.
