A model predictive control method with terminal invariant ellipsoid constraints is proposed for time-delay systems with constrained control input. The stability of the closed-loop system is guaranteed by constructing specific objective functions and terminal invariant ellipsoid for time-delay systems. The sufficient conditions of stability are presented in the form of LMI (Linear Matrix Inequalities)that makes the scheme simple to be realized. The simulation results verify the effectiveness of the proposed method.
