状态变量观测与控制在主汽温度控制系统上的应用

提出了把现代控制理论的状态变量观测与控制系统理论应用于主汽温度控制系统的方案和参数整定方法。通过仿真试验得出了它的特点，状态变量观测与控制系统能较大地改善过热汽温的控制品质。在长兴发电厂5号机组的主汽温控制系统中得到了应用。

This paper put forward the scheme applying modern control theory-state variable quantity observation and control to boiler's main steam temperature control system as well as parameter tuning method. The characteristics of the control system is obtained via simulation test that state variable quantity observatinn and control syStem can improve control quality of boiler's main steam tempeature. It has been success faily applied to the main steam temperature control system in Changxing power plant.
