Abstract:   Waterjet propulsion is an advanced propulsion technique for high speed ships. The robustness of its steering control system is an essential demand due to various disturbances. In this contribution, the mechanism transfer function model of the waterjet steering propulsion system is established first. Then, model based disturbance observer is designed and a global sliding mode controller is developed. Furthermore, the existence of global sliding mode and the asymptotically stability of the closedloop system are proved. Simulation results are presented to demonstrate the high precision of the disturbance observer, good tracking performances and strong robustness of the control strategy.
