Abstract :
The offshore jacket platform is a complex, time varying nonlinear system, which can be excited harmful vibration by the external load. A new kind of inverse control method, based on the combination of grey prediction and support vector machine, was given in this paper and applied to control the vibration of the offshore platform with dynamic stiffness matrix method efficaciously. The numerical results show that the new control method can decrease the vibration response of structure cased by the wave and wind load effectively, and solve the time delay problem caused by the control signal transmission.
