摘　　要：针对煤气炉风门人工控制无法达到较好控制效果的问题,提出了一种模糊PID自动控制设计方案;分析了系统控制过程并建立了被控系统的数学模型,根据建立的数学模型在Simulink中对控制效果进行了仿真,结果表明系统响应快、无超调,对负荷波动导致的压力变化抑制能力强;在系统输出施加振幅为400Pa,周期为50s的干扰时,可将压力变动稳定在60Pa以内;设计了基于高性能嵌入式计算机LPC2925的系统硬件电路结构及软件,该系统体积小易于安装,方便构成现场总线的控制系统,同时对控制系统进行了可靠性设计。Aimed at the problem that manual control for gas stove can not achieve good control performance,a fuzzy PID control design is given.The control process of the system is analysed and the mathematical model of controlled system is established,control effects are simulated in simulink according to the mathematical model,and the results show that the system,fast response,no overshoot,load fluctuations which lead to the pressure change are strongly restricted.Put the interference with amplitude 400Pa and period 50s in the system output,the system can be stabilized within 60Pa pressure changes.Hardware structure and software are designed based on high-performance embedded computer LPC2925,The system is small and easy to install,easy for fieldbus control system.The control system reliability was designed at the same time.
