摘要
针对考核机组过热汽温对象的迟延特性，采用静态增益变化的自适应Ｓｍｉｔｈ预估器，设计了一个过热汽温自动控制系统。仿真实验证明，系统调节器品质好，实现简单，组态方便。
presents a control system for the temperature of super-heatedteam in an imported 300MW steam power plant adopting a self-adaptive Smith predictor, in which the static gain of the controlled plant is changeable. The system is superior to some other common systems, according to boththeoritical analysis and simulation. It is valuable in both theory and parctice because of its easy realization and convenient configuration.
