摘要
过热蒸汽温度对象具有时变性、不确定性和非线性等特点,是联合循环余热锅炉中一个较难控制的过程。借鉴免疫系统原理,提出一种新的免疫并行算法,进而运用该算法提出一种PID参数优化方法,并将其用于余热锅炉过热汽温的优化控制中。仿真结果证实了该方法的有效性。
The superheated steam temperature of a combined cycle power plant＇s heat recovery steam generator （HRSG） is hard to control because of its variability with time, its uncertainty and its nonlinearity characteristics. According to immune system principles, a new immune algorithm to be used in para lel, is being presented, based on which a PID parameter optimizing algorithm is proposed and applied to optimize the control of HRSG＇s superheated steam temperature. Simulation results prove the method to be effective, Figs 9, table 1 and refs 9.
