STUDY OF IMMUNE PID CONTROLLER FOR SURPERHEATED STEAM TEMPERATURE CONTROL SYSTEM

A biological immune system responds to various antigens. Proper immune response coordinated by T cells is key to maintain the stability inside body. 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 in of immune PID controller are described. Simulation results obtained for the superheated steam temperature control system with parameters changing and perturbations demonstrate the effectiveness of the immune PID controller.
