1、引言 我们所熟悉的经典自动控制理论,是运用复频域的方法,对线性定常的单输入——单输出系统进行分析和设计。这样系统的输入——输出关系,是建立在传递函数的基础之上的。古典调节理论运用起来是比较简单的,但由于系统的设计是建立在试探法的基础之上的,因而通常是得不到最佳控制系统的。 1, Introduction We are familiar with the classical theory of automatic control, is the use of complex frequency domain method, the linear constant single input - single output system analysis and design. The input-output relationship of such a system is based on the transfer function. Classical conditioning theory is relatively simple to use, but the optimal control system is usually not available because the design of the system is based on heuristics.
