1.导言 在文献中的一系列工作研究了以受控对象的单位阶跃响应为基础的工业过程的简单数控方法。这些研究工作指出对于某些类过程来说,受控对象的数学模型容易从实验数据获得,并且有限调整时间的控制器与观察器增益可从数学模型直接计算出来。虽然在这种控制算法中包含了现代控制的概念,但是,这种方法并不需要对象的详细物理状态的空间模型,因此,当过程动态对于建立详细的物理模型来说太复杂了的时候,这种方法是特别引人注目的。
1. Introduction A series of work in the literature has examined a simple numerical control method for industrial processes based on a unit step response of a controlled object. These research work points out that for some classes of processes, the mathematical model of the controlled object can be easily obtained from the experimental data, and the controller and observer gains of finite adjustment time can be directly calculated from the mathematical model. Although the concept of modern control is included in this control algorithm, this method does not require a spatial model of the detailed physical state of the object. Therefore, when process dynamics are too complicated for establishing a detailed physical model, This method is particularly compelling.
