分散自校正控制算法及其全局收敛性分析

Decentralized Self-Tuning Control Algorithm and Global Convergence Analysis

本文基于分散控制和自校正控制的思想，提出一种大系统分散自校正控制算法．在研究某个子系统时，把其它子系统的影响等价为可测干扰，对各子系统采用本文提出的多变量自校正控制算法，从而实现大系统的整体控制．仿真结果表明对大系统采用分散自校正控制是行之有效的．算法的全局收敛性和参数估计强相容性也得到了证明．

In this paper,a decentralized self-tuning control algorithm of large scale system is presented based on the idea of decentralized control and self-tuning control. When studying a subsystem, we consider the interactions as mesurable disturbances. The multivariable self-tuning control algorithm is used for every subsystem, by this way we realize complete control of a large scale system. Simulation redults show that it is applicable to control a large system by using decentralized self-tuning control. Global convergence and strong consistency of paremeter estimatis are given.
