摘　　要：为解决煤气加热炉由于燃料压力变化和进出料时引起的炉温波动,将模糊串级控制应用到炉温控制系统中。该文分析了加热炉的对象特点和引起炉温波动的因素,介绍了参数自整定模糊PID调节原理,设计了基于组态软件、串级控制和智能仪表的炉温模糊控制系统。实验结果表明:串级控制是解决这类问题的有力工具。该控制系统具有静态精度高、自适应能力强、可靠性好、抗扰动性强的特点,大大提高了炉温的控制质量。In order to solve the problems of furnace＇s varieties caused by gas pressure,the string fuzzed-PID controller was investigated in the temperature control system.After the analysis of the furnaces characteristics and the factors causing temperature variation,the fuzzy controller of self-adjusting PID parameters was presented and the fuzzy cascade control system based on configuration software,intelligence measuring appliance and cascade control was investigated in gas furnaces.The results showed that the good effects were achieved by the cascade controller and this temperature control system has the characteristics of static accuracy,adaptability,reliability,and anti-interference.
