摘　　要：针对变截面板簧轧机厚度自动控制系统这一类非线性、时变的复杂系统,利用模糊算法的强鲁棒性以及根据人类免疫系统而设计的免疫算法,提出了模糊免疫PID控制方法。这种控制方法不需要建立控制对象精确的数学模型,是一种具有鲁棒性强、实时性强的智能控制策略。仿真实验证明:在模糊免疫PID控制器的控制下的AGC系统具有了高响应速度,超调量小,抗干扰能力强的响应特性。Aiming at the automatic gauge control of variable cross - section rolling system, which is a strong non - linear and time - varying system,this paper utilizes the strong robustness of fuzzy algorithm and the immune algorithm designed according to the human immune system. A new fuzzy immune PID control method is proposed. This controlling method does not need to establish the controlled object＇ s ac- curate mathematical mode. And it is a kind of intelligence control strategy that with strong robustness and fine timeliness. In the fuzzy immune P I D controller under the control of AGC system, a good perform- ance is proved by the computer simulation that show the high speed of response, small overshoot, strong anti -interference ability response characteristic.
