For the state feedback model predictive control system design, the disturbance decoupling problem is studied. For the undetectable or immeasurable disturbance, necessary and sufficient conditions are given for the disturbance decoupling problem design of the state feedback model predictive control systems. The design procedure is given step by step for choosing the design parameter to improve both the control performance and the disturbance rejection ability. Simulation results show the disturbance decoupling problem design is effective for the state feedback model predictive control system design.
