A new idiotypic immune network based PID controller design

Artificial immune systems are widely studied. The paper analyzed the stimulation and suppression relationship between antibodies and antibodies versus antigen in an idiotypic immune network, and explained the relationship of PID controller parameters in different phases of control process in the view of analysis above. Based on the explanation, the paper presented a PID control scheme with mechanism of idiotypic immune network regulation to adjust the controller parameters dynamically during the antigen suppression. A method was introduced to overcome the hypersensitivity resulted from high antibody concentration under the condition of repeat antigen invasion. The simulation results to some systems show that the scheme could shorten the calculation time and have the systems controlled effectively.
