摘要:

基于生物免疫系统的反馈机理,针对现有免疫反馈算法在系统超调后性能恶化的不足,提出了一种新型的免疫反馈算法。该算法考虑了系统超调后的免疫响应过程,补充给出了系统超调初期、中期及后期的免疫规则。仿真结果表明,基于新型免疫规则的PID控制器超调更小、响应更快,抗干扰能力强,十分适用于大惯性对象和超调量大的系统。

Abstract:

Based on immune feedback mechanism of biological immune system,a new immune feedback algorithm was carried out in order to overcome the disadvantages of present immune feedback algorithm in overshoot state.The response after overshoot was considered in the new algorithm,and the immune feedback rules of different period of response progress especially when overshoot was presented.Results show that the new immune PID controller has faster response,less overshoot and better ability of anti-jamming,which is suitable for those system that has large inertia or overshoot.
