| Abstract: | Aiming at the linear time-invariant system under noise condition, predictive control algorithm is presented based on optimal information fusion Kalman filter. By using the optimal information fusion Kalman filter in the linear minimum variance sense, the state estimators are derived. Further more,N steps ahead output pre- dictions are obtained. Finally, the control inputs based on information fusion state estimators are calculated by minimizing the quadratic cost. A simulation example illustrates the efficiency of this method. |
