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 (<i>u<sub>d</sub></i>, <i>u<sub>q</sub></i>) 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 (<i>V<sub>pvdc</sub></i>) and reactive current (<i>i<sub>q</sub></i>). 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.},
