Disturbance Suppression in Attitude Control of Raft System Using Air Spring

Abstract:

Though air spring greatly improves the isolation efficiency of raft isolation system, the technological problem occurs as how to maintain raft attitude balance. This paper set up an analysis model of raft attitude disturbance, and analyzed the influence of various disturbance sources on raft attitude, including hull rolling, systematic load variation, and air spring leakage. It proposed to control raft attitude through adjusting the pressure of air spring isolator, and then studied the feasibility of this method. The results show that the influence of various disturbance sources could be canceled effectively by adjusting the pressure of air spring isolator, thus maintaining attitude balance.
