最小方差关连控制设计

本文讨论了最小方差关连控制设计问题,在随机干扰作用下系统需设计为最小方差,以抑制干扰和跟踪输入信号,本文将最小方差应用于关连设计,将各子系统之间的关连看成是可变的,且将各子系统的关连看成是回路反馈,以最小方差进行反馈设计,这里出现的新问题是反馈通过了多个控制器闭合,需同时使各子系统皆运行在最小方差状况下。文中以具有二子系统和二控制器的关连反馈为例、得到了最小方差关连控制的实观条件。文中给出了例题以示该方法的应用。这一方法对强关连系统提出了新的设计思想:一种将关连考虑在内的综合设计思想。

MINIMAL VARIANCE INTERCONNECTION CONTROL DESIGN

In this paper the minimal variance interconnection control design problem is introduced. When the stochastic perturbance is existed, system must be designed on minimal variance In the paper the minimal variance design is used in interconnection control. The interconnection between the subsystems is treated changablc, and as a loop feedback through more than one subsystem. the design of interconnection becomes a minimal variance feedback design. In the paper, the system with two subsystems and two controllers is discussed. The solution of minimal variance feedback is obtained. The example was given to illustrate the application.
