This paper,taking ship fin stabilizer control system as an object,applying fuzzy control theory,has come up with a PID parameter self-adjusting controller based on fuzzy reasoning,so as to realize the theory of on-line controller parameter fuzzy sel-adjusting.Moreover,the system is simulated with the non-linearity of ship model and different wave directions taken into account.Simulation results show that,compared with conventional PID controller,the PID parameter self-adjusting controller based on fuzzy reasoning is of much better control effects and stronger robustness.
