Identification of Dynamically Positioned Ships
Todays model-based dynamic positioning (DP) systems require that the ship and thruster dynamics are known with some accuracy in order to use linear quadratic optimal control theory. However, it is diicult to identify the mathematical model of a dynamically positioned (DP) ship since the ship is not persistently excited under DP. In addition the ship parameter estimation problem is nonlinear and...
متن کاملComments on "Nonlinear output feedback control of dynamically positioned ships using vectorial observer backstepping"
The decomposition of nonlinear output feedback control into an observer and a state feedback control is an open problem. A solution for dynamic positioning of ships has been proposed in 1] and 2], where an observer-based back-stepping method is used. This note points out that the observer design in 1] and 2] does not cover unstable ship dynamics and suggests a remedy for an extended class of sh...
متن کاملAdaptive identification of dynamically positioned underwater robotic vehicles
This paper reports a stable online adaptive identification technique for the identification of finite-dimensional dynamical models of dynamically positioned underwater robotic vehicles. Proofs for the identifier’s global stability, and for the input-tostate stability of this class of plants are reported. A direct comparison of the adaptive identification method to a conventional, offline, least...
متن کاملPreliminary experiments in the adaptive identification of dynamically positioned underwater robotic vehicles
This paper presents a stable on-line adaptive identification technique for the identification of finitedimensional dynamical models of dynamically positioned underwater robotic vehicles. A direct comparison of this method to a conventional, off-line, least-squares method is presented. Using experimental data obtained using the JHU Remotely Operated Vehicle, both methods are employed to develop ...
متن کاملTechnical Problem Identification for the Failures of the Liberty Ships
The U.S. Liberty Ship Building Program in World War II set a record—a total of 2700 Liberty Ships were built in 6 years, in order to support the battle against Nazi-Germany. However, numerous vessels suffered sudden fracture, some of them being split in half. This paper demonstrates and investigation of the Liberty Ships failure and problems, which reveals that the failures are caused by a comb...
