摘　　要：针对锅炉汽包水位动态特性的不确定性,建立锅炉汽包水位系统的数学模型,设计以误差和误差变化率为输入,以PID控制器的3个参数为输出的汽包水位模糊自适应PID控制器。通过Matlab中的Simulink工具箱对系统模型进行仿真实验和分析,结果表明:该系统在汽包水位控制的响应速度和控制精度等方面都有较好的效果。As to the uncertainty of dynamic characteristics for the boiler drum water level,the mathematical model of the boiler drum water level system is established.Fuzzy adaptive PID controller is designed,which concludes two inputs（error and error change rate）and three outputs.The simulation experiment of the system is carried out by using the Simulink toolbox of Matlab.The results show that the scheme has fast response and high precision,and at the same time,it has better control effect on the false water level.
