摘　　要：针对三冲量工业燃气锅炉汽包水位控制系统非线性、多扰动的特点,设计了改进不完全微分和自适应模糊PID复合控制算法,用于抑制系统扰动产生的振荡以及对控制参数进行实时整定,实现对系统的快速、精确控制。通过Matlab仿真结果表明:本文设计的改进不完全微分自适应模糊PID控制的超调量为0,系统无振荡,上升时间为0.51s,调节时间0.7s,其控制性能优于普通模糊PID控制和常规PID控制。该控制算法为锅炉汽包水位的精确快速控制提供了一种有效方法。Aiming at the characteristics of nonlinear and multi - disturbance of the three - variable industrial gas - fired boiler drum water level control system.The improved incomplete differential and adaptive fuzzy - PID compound control algorithm was designed to eliminate the oscillations generated by the system disturbance and to adjust the eontrol parameters in real time ,then achieve rapid and precise control of the system. The resuhs of Matlab simulation show that the overshoot of this improved differential and adaptive fuzzy - PID compound control was 0,the system has no oscillation, the rise time was 0.51s, the adjustment time was 0.7s. Its eontrol performance was better than ordinary fuzzy PID control and conventional PID control. That provided an effective method for precise and rapid control of boiler water level.
