Abstract

The proposed controller accompanies with different sliding surfaces. To understand maximum power point extraction as opposed to nonlinear uncertainties and unknown disturbance of a grid-connected photovoltaic system to various control inputs (ud, uq) is designed. To extract maximum power from a solar array and maintain unity power flow in a grid by controlling the voltage across the dclink capacitor (Vpvdc) and reactive current (iq). A multiple input-output with multiple uncertainty constraints have considered designing proposed sliding mode controllers to validated their robustness performance. An innovative controller verifies uncertain inputs, constant and changes in irradiances, and temperature of the photo-voltaic system. These controllers do not limit the parametric uncertainties and disturbances on the system, which shows the significance of the developed designs. The performance characteristics have been compared to two sliding mode controllers and validated through numerical simulation for both normal and robustness conditions.
