Resumo

Maximum power point tracking (MPPT) is a technique to find the maximum power from a photovoltaic (PV) system, however, in fast variation environment conditions it loses performance. This article proposes a sliding mode (SM) controller applied to the dc-dc boost converter of a PV system to improve performance. The proposed controller consists of two control loops: input voltage control loop oriented by MPPT algorithm to calculate the inductor current; and current control loop to calculate the duty cycle of the frequency switch. Experimental results using a solar kit are presented to verify its performance and results are compared with lead-lag and SM plus proportional-integral (SMPI) controllers showing a reduction of steady-state error, overshoot, and settling time.
