Disturbance decoupling problem of state feedback model predictive control

For state feedback model predictive control system design, the disturbance decoupling problem is studied in detail. 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 system. We consider the disturbance decoupling problem and state space model, the design procedures are given step by step for choosing the design parameter-the prediction horizon. A simulation example is given, the simulation result shows that both the control performance and the disturbance rejection ability are improved and the control system design procedures are effective.
