Abstract
Digital control problems for dynamically positioned ships are considered by nonlinear sampled-data control theory based on Euler approximate models. State feedback laws that guarantee semeglobal practical asymptotic (SPA) stability of ships are designed. Then the reference signals for the position and the attitude of ships are introduced and state feedback tracking laws are also designed. The effectiveness of the designed feedback laws is demonstrated via experiments by using a small test boat.
