This article proposes a finite-set quasi-sliding model predictive control (FS-QSMPC) scheme for LC-filtered VSIs to improve the output-voltage quality. By explicitly including a predictive sliding-mode function into the cost function, reduced steady-state ripple and enhanced robustness are achieved compared to typical FS-MPC. Besides, theoretical analysis of stability and robustness for FS-QSMPC is given. Analytical tuning of the weighting factor is also derived to decrease the tuning effort. Comparative simulations and experiments verify the presented approach. © 1982-2012 IEEE.enModel predictive control (MPC)Sliding mode control (SMC)Stability analysisWeighting factor (WF)ArtículoAtribución-NoComercial-SinDerivadas 3.0 Chile (CC BY-NC-ND 3.0 CL)10.1109/TIE.2021.3135605
