区间数及在控制系统中的应用

Interval Numbers and Interval Control System for Application

在生产过程中,有些控制系统中的参数不是常数而是一个区间时,与常规的方法有较大的不同.本文以一阶系统为例,在MATLAB环境下用INTLAB软件编程建立运行区间系统,获得采用PI调节器进行校正后其系统的输出响应,并用仿真结果的变化来确定区间系统的最优控制参数.

In production line, when the parameter of control system is not a constant but a zone,it is more different from normal regulations. In this text, we show a first-order system for instance. We use INTLAB software under the environment of MATLAB to establish and run the interval system to obtain the output response of system after it is corrected by PI modulator and to determine the optimal control parameter of the interval system using the variation of emulating result.
