离散时滞大系统的最优跟踪递阶控制方法

Optimal Tracking Hierarchical Control ofTime-delay Large-scale Systems

考虑具有控制时滞及输入输出之间前向通道的大系统，应用线性二次型加积分（ＬＱＩ）［１］的最优状态反馈控制理论和带时滞增广状态向量方法，转化原大系统为满足马尔可夫性质的增广状态大系统，再作子问题分解后［２］，整个大系统的解可由子问题层的局部控制器和上层协调器迭代计算。

The large-scale systems with control time-delay and direct path between input and output variables is considered. Using the optimal feedback control theory of linear quadratic integral (LQI) and augment state vector method involved all the time-delay variables to convert original systems into corresponding augmented large-scale systems satisfying Markov processes, which can then be further decomposed into a series of sub-problems, the entire system's solution is finally given optimal tracking hierarchical control algorithm by the iterative computation between the sub-problems being the local control level and the coordinator.
