水压灰色预测控制研究

On Grey Forecasting Control of Water Pressure

针对某供水系统的工况及水压控制的要求，分析了供水系统的特点。认为供水系统具有灰色特征，提出了水压灰色预测控制方案。通过计算机进行灰色预测控制仿真，显示超调量小，调节时间短，控制效果优于单一ＰＩＤ控制。

The characteristics of a certain water supply system are discussed with respect to the op-erating conditions and control requirements,It is pointed out that the system is characterizedby nonlinearity,high order,pure time-lagging and uncertainty. The controlled processshould be a grey system according to the grey theory.A grey forecasting PID control schemeis proposed.The results of computer simulation show that the maximum overshoot is small-er and the settling time required is shorter as compared with single PID control.
