摘　　要：根据生物免疫系统特性 ,提出了一种基于免疫进化算法的PID控制器参数自整定方法。免疫进化算法引入记忆细胞和抗体浓度调节机制 ,具有种群多样性 ,能保证快速稳定地收敛到全局最优点。通过对过热汽温控制系统的仿真 ,表明该算法是有效的。In accordance with biological immune-system characteristics the authors have come up with a method of self-tuning PID controller parameters on the basis of an immune evolutionary algorithm. The immune evolutionary algorithm has introduced memory cells and features diversity and an anti-body concentration regulation mechanism, ensuring a rapid and stable convergence to attain an overall optimal point. A simulation of the superheated steam temperature control system has demonstrated the validity of the recommended algorithm.
