This paper addresses the problem of voltage regulation by multiple DC/DC converters and without communication amongst the converters. In DC systems where multiple different energy storage devices need to regulate a common DC bus while executing their individual battery management algorithms, it is necessary to find an automatic mechanism to coordinate how the different converters share the responsibility...
Using a nonlinear converter model, a numerical on-line optimization free model predictive control (MPC) is proposed for a converter to regulate the capacitor voltage. The MPC is given analytically by minimizing an energy function of the tracking error with its global exponential stability under input constraints. The outer-loop PI controller is adopted to eliminate an offset errors caused by a plant-model...
This paper presents the design and simulation study of a proton exchange membrane fuel cell based distributed generation system. The topology chosen for the simulation consists of fuel cell power plant model, pulse width-modulation DC/DC boost converter and sinusoidal pulse width-modulation two-level inverter followed by an LC filter. Advanced control strategy is used for the overall system; its main...
