摘　　要：针对火电厂再热汽温控制系统的大惯性、大迟延和时变性,设计了基于逻辑规则控制算法的再热器温度控制系统。仿真研究表明,该策略的控制效果优于常规的PID控制,能适应对象参数的变化并表现出良好的控制品质,具有较强的鲁棒性和自适应能力。Considering the characters such as inertia, long delay and time-varying of superheated steam temperature in the ther- mal power plant, reheat steam temperature control based on logic rule control algorithm is desiged in this paper.This method has provided a much preferable controlling effect than conventional PID control.What＂ more,it not only have a per- fect adaptation to the change of object parameter and perform an excellent control character,but also have a strong ro- bustness and self-adaptability.
