摘要
针对焦炉温度大惯性、纯滞后、非线性和时变性等特点,结合PID和模糊控制两者的优点,提出了一种模糊自适应PID控制方法.对模糊自适应PID算法进行了理论分析,对焦炉生产的简化模型做了仿真研究.结果表明,采用模糊自适应PID控制,系统的调节时间缩短,响应速度加快,抗干扰能力和适应参数变化的能力都优于常规PID控制,具有更好的动态特性和稳定性,有效减少了炉温的波动.
Combining both the advantages of PID controller and fuzzy control, a fuzzy adaptive PID controller is proposed for the characteristics of coke oven, such as big inertia, pure time-delay, nonlinearity and time-varying. The algorithm of fuzzy adaptive PID control is analyzed theoretically and the simplified production model of coke oven is simulated. The results showed that such a fuzzy adaptive PID controller has the advantages of shortening the time for system readjustment, quickening the response speed, higher anti-interference ability and adaptability to parameters＇ changing than conventional PID controller and better dynamic property/stability. All these can reduce effectively the fluctuation of coke oven temperature.
