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。
In this paper, we discuss the design of minimum variance control. Under the random disturbance, the system needs to be designed as the minimum variance to suppress the interference and track the input signal. In this paper, the minimum variance is applied to the design of the connection, and the connection between the subsystems is considered as Variable, and the connection of each subsystem as a loop feedback, the minimum variance feedback design, the new problem here is the feedback through a number of controllers closed, at the same time make the subsystems are running at the minimum variance Situation. In this paper, the related feedback with two sub-systems and two controllers is taken as an example, and the real objective condition of the minimum variance-dependent control is obtained. The article gives examples to show the application of this method. This approach presents a new design philosophy for a strongly connected system: a comprehensive design idea that takes into account the connectedness.
