A Decentralized Explicit Predictive Control Paradigm for Parallelized DC-DC Circuits

This paper extends previously introduced explicit optimal control methods for fixed frequency switched mode DC-DC converter circuits to the parallel synchronous step-down (i.e., buck) topology with N branches. Due to the computational complexity of modelling and controlling such potentially large multivariable systems a decentralized model predictive control scheme is employed allowing for the related optimal control problem to be efficiently formulated and solved offline for each local controller. Simulation results are provided to illustrate the outcome of the proposed approach.
