Abstract

In this paper the integration of the application of the Back-Stepping Control (BSC) strategy for the Maximum Power Point Tracking (MPPT) of photovoltaic (PV) systems is presented. The output voltage regulation and the MPPT control strategy is applied to a DC-DC Non-Inverting Buck Boost (NIBB). The robust and non-linear BSC is based on Lyapunov function for ensuring the local stability of the system. Further on, the basic idea of this later is to synthesize a recursive way control law step by step. Simulations are performed to validate the control strategy and analyze the performance. The obtained results show that the proposed solution, compared with the well known classical PI controller, exhibits lower transient overshoot, lower tracking error and fast response when solar irradiation and cell temperature occur.
