Design and simulation of fuzzy immune controller of fin stabilizer-passive anti-rolling tank integrated stabilization system

Aims at the mathematical module of ship integrated stabilization system, combines immune feedback mechanism with fuzzy control to design a fuzzy immune PID controller. Uses Fuzzy reasoning to approach the nonlinear function faintly in fuzzy immune controller and adjusts proportion gain of controller real-time, at the same time, uses general fuzzy controller to adjust integral and differential time constants of controller on line. Through simulation of the integrated stabilization system, it can be seen that using fuzzy immune PID controller can obtain better control effect than general PID controller, the integrated stabilization effect increased obviously.
