基于单片机的学习型专家系统水位控制器

锅炉汽包水位是一种非线性、时变大、强耦合的多变量系统。目前，锅炉的给水调节普遍采用PID控制器来进行控制，控制系统需要根据锅炉运行状况的变化而相应地调整PID参数，其整定值往往凭经验给定，不容易达到系统最好的控制效果。将智能控制理论应用于锅炉水位控制，不需求解系统复杂的数学模型，可以取得较好的控制效果。

Learning expert control on drum water level control system based on single chip microcomputer

The drum water level of boiler is a multiple variable system with nonlinear, big time varying and strong coupling characteristics. The PID controler are widely used in water level of boiler control system in present. The PID controler＇s parameter must be reset according to the boiler＇s working situation. The reseting parameter are usually based on human＇s practice. The system are hard to obtain the best state. This paper introduces intelligent control theory into water level of boiler control system. So that, the system＇s math model was needed not to acquired. The system still can acquire better result.
