This thesis presents the development of an RMRAC-STSM control structure, composed by a robust model reference adaptive controller (RMRAC) along with an adaptive Super- Twisting Sliding Mode (STSM) controller. A continuous and discrete-time stability analysis of the proposed control structure is presented, showing its stability and robustness in face of unmodeled plant dynamics. In addition, the proposed controller is used to regulate the grid-side currents of a three-phase grid-tied converter with LCL filter. The obtained Hardware in the Loop simulation results and experimental results are compared with RMRAC and RMRAC-SM controllers.
