自动控制系统中被控参数的预测

通过对工业过程控制系统中被控对象过渡过程特性的分析，针对其规律特点提出：依据所测试的过程参数的一系列历史数值预估该参数的发展趋势及数值的大小，为控制决策指明了方向。特别是对于具有大惯性、纯滞后的被控对象的控制系统，运用参数预估，增加预估反馈环，能够克服许多控制上的困难，取得好的控制效果。

Controlled parameters estimation in automatic control system

This paper analyzes the characteristic of transient process of controlled plant in industrial process control system. On the measured history numerical values of process parameter, estimating developing tendency and numerical value of these parameters is done.For those control systems, that controlled plants have larger inerta and delay action, better control result can be achieved using the method of estimating parameters.
