摘　　要：结合模糊控制与常规PID控制,针对焦炉的大惯性、滞后、时变、非线性等特性,提出了模糊自适应PID控制,并应用到焦炉加热。借助焦炉数学模型进行了仿真分析,结果表明,与常规PID相比,模糊自适应PID能够减小超调量,缩短响应时间与调整时间,抗干扰能力更好。In consideration of the characteristics of fuzzy control and conventional PID control and according to the large inertia,delay,time-varying and non-linear of coke oven,etc.,adaptive fuzzy PID control was put forward and can be applied for coke oven heating. The simulation analysis for coke oven mathematical model showed that the adaptive fuzzy PID can reduce overshoot,shorten the response time and adjustment time as well as better anti-interference ability.
