Research on wave disturbance in integrated control system

Because of the effect of marine environment on integrated control systems, an accurate wave model is the basis of integrated control system. In order to effectively calculate the forces and moments acted on the integrated control system by marine environment and optimize controller, the paper uses equi-energy divided method to build the mathematical model of wave disturbance based on Matlab. Furthermore, a simulation based on a supply ship is carried out, under different sea states,wave interference torque on the ship is researched. The results show that this method can simulate wave quickly, accurately and effectively, and the effect of this model fits actual mechanical experience well.
