An efficient predictive current controller with adaptive parameter estimation in 3-ϕ inverter

In this paper, a detail design and description of predictive current control scheme are adopted for three-phase grid-connected two-level inverter its application in wind energy conversion systems. Despite advantages, the controller is very sensitive to parameter variations which could eventually affected on system stability. To solve problem, an estimation technique proposed identify value harmonic filter based Model reference adaptive (MRAS). Lyapunov stability theory selected guarantee robust adaptation stable response over large variation. The simulation results shows efficiency techniques improve tracking performance.
