The problem of optimal switching between different topologies in step-down DC-DC voltage converters is investigated. Different challenges including presence of line and load disturbances as well as constraint on the inductor current are incorporated. The objective is generating the desired voltage with low ripples and high robustness towards the disturbances. The selected tool is a previously developed...
Optimal switching between different subsystems with discrete-time dynamics subject to a minimum dwell time constraint is investigated in this study. A feedback solution, using the framework of approximate dynamic programming, is proposed through tuning parameters of a function approximator. Once tuned, online control will be conducted with a computational load as low as evaluating a few scalar-valued...
