IMPROVEMENT IN STEERING CONTROL FOR MERCHANT SHIPS

The problem of developing a practical autopilot for all-weather steering in high speed merchant ships is analyzed and broken into four smaller problems: Specification of realistic models for the elements involved; identification of ship model parameters; development of a suitable adaptive control algorithm for the nonlinear stochastic system comprising the ship, its steering engines and the seaway disturbance model; and finally, a review of the developed algorithms with the objective of eliminating nonessential computations thus improving the computational efficiency.
