This paper presents a novel robust & adaptive sliding mode (SM) control for a cascaded two-level inverter (CTLI)-based grid connected photovoltaic (PV) system. The modelling and design of the control scheme for the CTLI-based grid connected PV system is developed to supply active power and reactive power with variable solar irradiance. There are two different switching schemes have been used to design the SM controllers. The performance of the SM controller is improved by using an adaptive hysteresis-band (HB) calculation. To improve the performance of SMC further, the present work develops a fuzzy controller for a nonlinear system allows for a reduction of uncertain effects in the system control and improve the efficiency. The controller performance is found to be satisfactory for both the schemes at considered load and solar irradiance level variations in simulation environment. The proposed controller is found to be capable of implementing the control algorithm successfully in the considered situation.
