Abstract
In this paper, a new fuzzy adaptive integral sliding mode controller is designed for suppressing the oscillation amplitudes of offshore platform subject to nonlinear wave-excited forces and parameter perturbation. First, an uncertain dynamic model of the offshore platform is considered. To overcome the constraint of the knowledge of offshore platform model, a new fuzzy adaptive integral sliding mode controller is proposed that is a combination of sliding mode as a robust controller, fuzzy mechanism as a universal approximator and an adaptive control law. In comparison with some existing controllers, the proposed control scheme requires much less control force and the vibration amplitudes are reduced significantly. This controller is designed based on solving a set of linear matrix inequalities. Finally, the simulation results show the effectiveness of the proposed control scheme.
