摘　　要：线性离散信息融合预见控制算法本质上是一种状态反馈最优控制算法,针对实际工程中部分状态不易直接测量的问题,研究了基于状态观测器的线性离散信息融合预见控制算法,并证明了在该算法中运用观测器设计状态反馈仍然具有分离特性,控制律和观测器的设计互不影响。通过将观测器的所有极点配置到原点,可以让观测状态的初始估计误差快速收敛。基于吊车系统的仿真研究表明了运用观测器设计信息融合预见控制系统的有效性。Linear discrete information fusion control algorithm is a essential state feedback optimal control algorithm,aiming at part of the states that is not easy to directly be measured in practical problems. A linear discrete information fusion control algorithm based on state observer is researched,and it is proven that observer used to design the state feedback still has the separation characteristics in the algorithm. The design of the control law and observer are not interactively affected. The estimation errors of the initial observed state can convergence to zero quickly by configuring each pole of observer to the origin. The simulation research based on a crane system shows that observer used to design the information fusion preview control system is effective.
