This study proposed an adaptive double‐integral‐sliding‐mode‐controller‐maximum‐power‐point tracker (DISMC‐MPPT) for maximum‐power‐point (MPP) tracking of a photovoltaic (PV) system. The objective of this study is to design a DISMC‐MPPT with a new adaptive double‐integral‐sliding surface in order that MPP tracking is achieved with reduced chattering and steady‐state error in the output voltage or current. The proposed adaptive DISMC‐MPPT possesses a very simple and efficient PWM‐based control structure that keeps switching frequency constant. The controller is designed considering the reaching and stability conditions to provide robustness and stability. The performance of the proposed adaptive DISMC‐MPPT is verified through both MATLAB/Simulink simulation and experiment using a 0.2 kW prototype PV system. From the obtained results, it is found out that this DISMC‐MPPT is found to be more efficient compared with that of Tan's and Jiao's DISMC‐MPPTs.
