| 摘 要： | 电厂主汽温控制对象有大惯性、长迟延、时变性的特点。为了提高火电机组的经济性和安全性，通常对主汽温控制系统提出较高的性能指标，但使用传统PID串级控制方法并不能取得更好的性能。为了改善主汽温PID控制器调节品质，运用模糊规则设计了一种新的模糊整定方法，介绍了基于MCS89C52单片机的相应硬件电路结构与软件设计。仿真结果表明，该模式在变工况时，通过在线修正控制器参数使控制系统性能指标几乎不变，对工程应用有实际意义。

| Abstract: | The main steam temperature controlled object has large inertia,long time lag and time-variation in thermal power plant.In order to enhance the economy and safety of thermal power plant,it is usually required that the main steam temperature control system should have higher performance indexes.However,better performance can not be achieved with traditional control methods which use the normal PID cascade control.In order to improve the regulation quality of the PID controller of main steam temperature,a new ... |
