Advanced Passivity-Based Control for a Fuel Cell/Super-Capacitor Hybrid Power System

To solve the converters coordination problem of a fuel cell/super capacitor hybrid power system, an advanced passivity-based control is proposed in this paper. The Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) is applied to design the controller. This nonlinear controller considers the state of charge of super capacitor and achieves the stability of the whole closed-loop system. Its feasibility for an electrical vehicle is proven by the simulation results and the comparison with the previous method.
