摘　　要：将基于模糊神经网络的PID控制器作为给水控制系统的锅炉汽包水位调节器,可实时整定PID控制器的参数,以适应控制系统的要求。仿真结果表明,基于模糊神经网络的PID给水控制系统的响应快速性、调节平稳性及抗干扰能力均优于常规的PID控制器。The PID controller based on fuzzy neural network is adopted as a regulator in the boiler drum＇s water - level control system, the parameters of PID controller can be set in real - time, so as to suit the requirements of control system. Results of emulation show that the PID feed - water control system based on fuzzy neural network is more excellent than conventional PID controller in aspects of response rapidity, regulation stability, and anti- interference ability.
