摘　　要：生物免疫系统是一种在大量干扰和不确定性环境中都具有很强鲁棒性和自适应性的系统。灰色预测具有少数据、贫信息且运算量小的优点。将灰色预测、免疫系统与常规PID控制三者的设计思想融合起来,提出一种灰色预测免疫PID控制策略,并将其应用到火电厂主汽温控制系统中。仿真研究表明,该控制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。The biological immune system that has strong robustness and self-adaptability in circumstances full of disturbances and uncertainties, and the grey prediction that has advantages of less data, information, and calculation work, are integrated together with the traditional PID control, and a novel immune PID control strategy based on grey prediction is proposed. The strategy was applied to the main steam temperature control system of power plants, and simulation shows that the novel control strategy is adaptive to the object＇s parameter variations, and its controlling performance is better than that of the traditional PID control strategy.
