  • A state feedback robust control algorithm is presented for ship steering autopilot with uncertain nonlinear system based on known parameter bound of the system and known bound of input disturbance by use of the theory of Lyapunov stability. Owing to not all states of ship motion being achieved and only ship course can be measured on board, so a high gain observer is proposed to estimate the states of ship motion and then a output feedback robust control algorithm is developed. An example illustrating the method described is included for ocean going training ship. It is shown that the controller can make the designed system guarantees the satisfied performance by simulation based on the Matlab Simulink package.
