- Abstract
- This paper describes the design steps of robust QFT autopilot for the course-keeping and course-changing control of a ship, in the presence of disturbances. The ship model has parametric uncertainties, caused by the variations of hydrodynamic coefficients with the speed of the ship. Knowing the variation ranges of the model parameters, the QFT method (Quantitative Feedback Theory) can be used to design the ship autopilot with certain performance specifications. The autopilot must satisfy the robust stability, tracking performance and disturbance rejection conditions, for all ship models generated by the parameter variations within the uncertainty ranges.
