The system uses PID controller and fuzzy controller to design automatic control loops, a study of fuzzy three-element feed-water control system for a CFB municipal waste incinerator is introduced. The incinerator is faced with problems such as large-scale fluctuation of furnace heat load and low regulation resolution of main control feed-water valve. The fuzzy logic control system is applied to modulate PI control parameters according to steam drum water level to fit fluctuated heat load, the inner and outer control loops are realized in an asynchronous way to effectively decrease regulation time and improve regulation precision.

针对垃圾炉炉膛负荷波动较大，同时给水调节阀门执行机构的调节精度较低的现状，在传统三冲量串级汽包水位控制方式的基础上，采用模糊控制策略对内、外串级回路的PI控制参数进行分区域调整，强调了PI参数在被控参量处于不同范围时的分离作用，同时内、外控制回路采用异步控制方式，浙江大学硕士学位论文从而有效地减小了被控参量的调节时间，提高调节精度，使水位波动控制在△为士12~范围内。
