Abstract :
Based on input and output states, a construction method of the responding ship motion nonlinear mathematical model is presented. Comparing with state space model, the computation of responding ship model is simple, and the differential equation obtained can preserve the nonlinear effect. Then the mathematical model of the 5446TEU container ship is constructed according to its relative parameters and the trial voyage datas. Combined fuzzy logic with conventional PID, a fuzzy self-tuning PID controller is introduced. Applying the proposed controller to the 5446TEU container ship steering system, the simulation results show that the controller works in effect.
