Air spring has been increasingly applied in marine raft isolation system to acquire excellent vibration isolation effect. However, it is a key technical difficulty to keep attitude balance for the raft. The response characteristics of raft attitude have been analyzed in detail. The raft attitude controllability condition for air spring leakage fault is discussed. The analyzed conclusion lays a foundation for ascertaining control parameters and designing fault tolerant control strategy.
