一种线性离散时间大系统分散最优控制器设计方法

A Design Approach of Decentralized Controllers for Discrete-Time Large Scale Systems

本文针对离散时间定常大系统模型,提出了一种分散最优控制器设计方法,即限定状态反馈阵为分块对角形,采用梯度寻优的方法,求得各子系统的分散控制器。另外,为了比较,本文还给出了集中最优控制器结果。最后讨论了设计算例,

The linear discrete-time large scale systems (LSS) is discussed here.An approach is proposed for the design of decentralized optimum controllers of systems, in other words, the feedback gain matrix K is restricted to be block diagonal, and the parameters of K is selected to get the disperse controller of sub- system by means of the gradient technique and the feasible direction method. In addition, the optimal controllers are given for comparison. At last, two illustrative examples are presented.
