摘要：Ship dynamic positioning refers to ship which singly keeps its fixed position on the sea by its own installation propeller without anchor. Backstepping design method using in the uncertainty system is a kind of systematic controller synthesis method and is a regression design method which combine the selection of the lyapunov function with the design of the controller. This paper begin with the minimum order differential equation of the system, then introduce the concept of virtual control and design the virtual control meeting the requirements step by step, in the end design the real controller according with the required index. At last establish the modeling and simulate in the Matlab, realize the Backstepping control in combination with S-function. The simulation results suggest that we can use Backstepping method to realize the control of the ship dynamic positioning system.
