摘　　要：汽包水位的控制以前大多采用常规PID控制方式,其控制参数是固定不变的,不能进行在线调整。对现行的先进汽包水位控制如自适应控制、专家控制、遗传算法、模糊控制、神经网络及其组合方式进行了分析和总结,在常规PID控制中加入智能控制,可提高汽包水位控制的效果和质量。Currently, most drum levels are controlled by conventional PID, and their parameters are fixed and can＇t be adjusted on line. Advanced control methods have been analyzed and summed up, such as adaptive control and expert control and genetic algorithm and fuzzy control and neural network and their compound control Combined intelligent control with traditional control, the effect and quality of drum＇s level can be greatly improved.
