A recognition-intensified two-cell controller and its characteristic analysis
识别强化的双因子免疫控制器及其特性分析

The current immune controllers constructed completely based on the biological immune mechanism are all self adaptive,structure-changing and proportional controllers.They can not track the invariable input without an error.In this paper,based on the two-cell immune nonlinear feedback model for describing the biology function,and combining it with the control system characteristics,we present a structure form of a recognition-intensified two-cell immune controller. The theoretical analysis is then carried out for the first-order tracking ability of the recognition-intensified two-cell con- troller.Both the theoretical analysis and the simulation indicate that this immune controller can track the invariable imput with null error.The simulations were performed on a class of controlled systems with large values of time-delay,for testing the memory characteristic and the interference-rejection ability of this immune controller.
