Fuzzy-immune PID controller for ship steering autopilot

Based on the bionics theory of biological immune system, a P-type immune feedback controller is created to improve conventional PID controller performance. Combining with fuzzy PID control used in feedback control link, the controller parameters for ship can be adjusted by the rules of immune feedback principle and fuzzy logics.
