随着工业生产的发展,要求过程控制系统具有全程控制能力,或者能在较宽的范围内工作。然而几乎所有的被调节设备,其特性总是随着它的负荷、运行工况或者其它因素非线性地变化,某些特征参数甚至是成倍地变化。这样常规调节系统的一组固定调节参数,就很难满足调节品质的要求。为此出现了变参数调节装置,通过在线改变调节器的参数,来适应对象特性的变化。国内学者亦有将类似这种变参 With the development of industrial production, the process control system is required to have the full control ability, or can work in a wide range. However, almost all of the regulated equipment, whose characteristics are always non-linearly changing with its load, operating conditions or other factors, even some of the characteristic parameters vary exponentially. Such a conventional regulation system of a fixed set of adjustment parameters, it is difficult to meet the regulatory requirements of quality. For this reason there has been a variable parameter adjustment device, by changing the regulator parameters online to adapt to changes in object characteristics. Domestic scholars will also have such a variant
