This paper proposes a robust predictive control algorithm based on H∞ performance for uncertainty multi-rate control system. The upper bound γ of H∞ performance target for the multi-rate closed-loop system is derived by using linear matrix inequality approach, and the condition of the robust stability for the closed-loop system is obtained. The simulation results show the effectiveness of the proposed algorithm.
