摘      要：An MPC-based consensus algorithm is proposed for current sharing in Direct Current (DC) microgrids. The proposed controller also ensures that both the buck converter output voltages as well as the load voltages remain within an acceptable range. The MPC scheme is designed using the notion of so-called finite-step control Lyapunov functions. Moreover, a deadbeat stable estimator is developed for the current loads which are assumed to be unknown constants. In particular, the current loads are accurately estimated in one time step. The effectiveness of the proposed scheme is verified via an illustrative example. © 2018
