摘　　要：根据物理过程的特点,应用质量守恒、能量守恒及传热学原理,建立了过热汽温对象较为精确的动态模型,在此基础上,分别应用单神经元PID控制和模糊免疫PID控制策略,实现了PID参数的在线调节。仿真结果表明,两种控制方法都具有良好的自学习和自适应能力,鲁棒性强,但模糊免疫PID控制器响应速度更快,且结构简单,有很好的应用前景。The more precise dynamic model for superheated steam temperature is established according to the characteristics of the physical process, as well as the principle of mass and energy conservation, and the theory of heat transfer. Then the application of single neuron PID and fuzzy immune PID control strategy realizes the online adjusting of PID parameters respectively. Simulation results indicate that both of the control methods have strong self-learning, self-adaptive ability and robustness, but the fuzzy immune PID controller has the better application prospect with the faster response and simpler structure.
