Nonlinear sampled-data stabilization of dynamically positioned ships is considered by reduced-order observer-based emulation controllers. Using a backstepping technique, continuous-time state feedback stabilizing feedback laws for ships are designed and then under natural detectability assumption for ships linear time-invariant continuous-time reduced-order observers are obtained. Then combining an...
The design of reduced order observers and reduced order observer-based output feedback stabilizing controllers for dynamically positioned ships are considered. Under the natural detectability assumption for ships given in [8], linear time-invariant reduced order observers for dynamically positioned ships are given by applying the design method of reduced-order observers for linear systems. Then using...
