| In this paper, the power electronic interface between a DC hybrid power source with a photovoltaic main source and battery storage as the secondary power source is modelled based on the state space averaging method. Subsequently, sliding mode controller is designed for maximum power point tracking of the PV array and load voltage regulation. Asymptotic stability is guaranteed through Lyapunov stability analysis. Afterwards, Three common control methods (LQR, PID, PBC) are provided to compare the results with those of the proposed sliding mode controller responses. Simulation of the hybrid system is accomplished using MATLAB and results of the proposed system are very promising. |
