Summary: | In this paper, an interconnection and damping assignment passivity-based control (IDA-PBC) theory is employed to obtain maximum power point tracking (MPPT) for a photovoltaic (PV) module. A current control mode is selected to obtain the general control law, which guarantees exponential stability of the system in the sense of Lyapunov. The current is selected as the objective of control in this paper, due to the variations of irradiance and temperature on the PV module to produce the most impact in the current provided by the panel in comparison with its voltage profile. A modification of the classical IDA-PBC theory is employed to control the dynamical system under trajectory tracking. Simulation results show the capacity of the proposed control to extract the maximum power from the PV module under high changes in the irradiance and temperature. All simulations are conducted in MATLAB/Simulink. © 2018 IEEE. |
