Study of Immune PID Controller for Wood Drying System

Appropriate response of immune system to variety antigen is the key organisms to maintain a stable internal environment. It mainly depends on the regulation of T cell. The function of T cells is both active and inhibitive, which provides immune system with fast response and adequate stabilization. Based on the immune system regulating law and comparison the control system and the immune system, an immune PID controller is proposed in this paper. The effects of parameters of immune PID controller are described. Simulation results obtained for wood drying control system with parameters changing and perturbations demonstrate the effectiveness of the immune PID control system.
