摘　　要：针对电厂主汽温度系统参数时变的特点,常规单控制器难以取得满意控制效果,提出了基于模糊多模型的专家PID控制方法。仿真结果表明,主汽温度在负荷变化的扰动下,能适应对象参数的变化并表现出良好的控制品质。Main steam temperature control system in thermal power plant features time-varying, for which the conventional control strategy generally can＇t satisfy excellent control effects. Expert PID main steam temperature control based on switching of multiple models was proposed. Simulation results show that the new control strategy is adaptive to the objects＇ parameter variations and has better dynamic characteristic than single model system.
