This paper proposes an improved model predictive control (MPC) scheme with a robust prediction and stability-constrained finite states for three-phase voltage source inverters (3&#x03A6;-VSIs) with an LC filter. In this paper, the stability-constrained finite states are selected via the asymptot...

To select the stabilized finite states, the stability conditions are derived by the equivalent feedback-gains and constrained in the exhausting search of the proposed finite-set (FS) MPC.
