摘要: 基于免疫原理，建立了一个基于免疫机制进行控制器参数整定的数学模型。给出了参数整定问题中抗原、抗体和亲和力的定义，对基于免疫原理的控制器参数整定过程进行了详细的描述。最后以PID的参数整定为例，控制一个高阶系统，大延迟系统和非最小相位系统。并与Z-N，MOMI等算法的整定结果进行了对比实验，结果表明该方法对控制器的参数整定是有效的。

Abstract: A mathematical model of controller parameter tuning based on immune theory is established. Antibody, antigen, and affinity of the parameter tuning problem are defined. The process of parameter tuning based on immune principles is discussed in detail. The method is used to optimize the three parameters of proportion-integral-derivative (PID) controller for the control of high-order process, large time delay process, and non-minimum phase process. The results compared with some other tuning methods show the effectiveness of the proposed method is effective.
