In this paper, we propose an efficient formulation of output feedback robust model predictive control algorithm for systems with polytopic uncertainty. The formulation is based on quasi-infinite cost function. First, we construct nested invariant ellipsoids and their corresponding state feedback gains; then we design a state estimator and establish closed- loop robust stability by proper choice of design parameters off-line. Next, we calculate the real time control law on-line, regarding to the current estimated state position in the state space. The proposed algorithm reduces conservatism of the available off-line methods due to the use of several Lyapunov functions and quasi infinite cost function. The algorithm is illustrated with an example .
