摘要
针对大滞后、大振荡受控系统的抗干扰及输出滞后问题,基于Varela免疫网络模型与控制系统的相似性,设计单输入单输出情形下的免疫控制器模型.在此控制器作用下,借助非线性系统理论,获得增广系统的稳定性以及受控系统的渐近跟踪特性.数值实验表明该受控系统可以快速跟踪参考信号且具有较好的抗干扰能力和抗滞后特性.
For the problem of anti-jamming and time-delay output of the controlled system with long lag and large oscillation, an immune controller model for the single input single output（SISO） system is designed based on the similarity between the Varela immune network model and the controlled system.With the help of the controller,the stability of the augmented system and asymptotic tracking characteristics of the controlled system are obtained by means of the theory of nonlinear systems.Numerical experiments show that the controlled system can quickly track the given reference signal and has good anti-disturbance and anti-lag performances.
