Designing and analysis of a immune controller based on the improvement Varela immune network model

Biological immune system is a control system that has strong robusticity and self-adaptability in complex disturbance and indeterminacy environments. The B cell and the antibody in biological immune dynamic process are described in the basic Varela immune network model (BVINM), but the antigen doesn't exist in this model. An improved Varela immune network model (IVINM) has been presented by appending the antigen in the BVINM in this article. Based on the improved Varela immune network model, an immune controller model is designed and its structure is proposed in the paper. The non-linear Varela immune controller singular point has been found and the non-error ability of tracking constant input has analyzed in the paper. Finally the paper gives a simulation example, and analyses the characteristic of the immune controller.
