摘要
针对一类变参数对象，本文提出了一种主、副调均采用鲁棒调节器的双环串级控制方法，并给出了这种系统的设计和整定步骤。应用该方法对某电厂变参数过热汽温控制的实例表明：该方法对一类变参数对象的控制具有很好的动态品质和鲁棒性。该方法还可推广应用于采用鲁棒调节器的多环串级控制系统。
in view of a kind of parameter-varying object, a new method is presented in which principal and subordinate robust regulators are used. The designation and setting method of system are also proposed. As the results of its application in the superheat steam temperature control of a power plant, this method has excellent control quality and strong robustness about parameter-varying system control.
