Maximum Power Point Tracking of Photovoltaic Systems Based on Fast Terminal Sliding Mode Controller

This workintroduces amaximum power point tracking method based on fast terminal sliding mode control (FTSMC) for photovoltaic systems. The control scheme contains two loops: the first achieves the maximum power point (MPP) searching via an algorithm which gives the reference voltage (MPV). The second loop achieves regulation of the operating point to the reference MPV issued from the first loop. Unlikely to the traditional sliding mode, the FTSM controller guarantees finite time convergence of the MPPT with robustness. Control performances are proved throw several simulations.
