We propose a robustly stabilizing Lyapunov-based control scheme for a Multi-Input Converter using a Nonlinear Disturbance Observer 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.
