Abstract
Recursive least square (RLS) algorithm applied to a multivariate auto-regressive (MAR) process is used to estimate ship steering dynamics online, and then linked to linear quadratic (LQ) algorithm to design an optimal autopilot for ships. Simulation results show the robustness of the estimation method and prove that the autopilot has very good performance during course-keeping and course-changing processes.
