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 کاملLimitations of nonlinear periodic sampled-data control for robust stabilization
This paper presents a performance analysis of nonlinear periodically time varying sampled-data controllers acting upon a linear time invariant plant. Time invariant controllers are distinguished from strictly periodically time varying controllers. For a given nonlinear strictly periodic controller, a time invariant controller is constructed. Necessary and sufficient conditions are given under w...
متن کاملStabilization of sampled-data nonlinear systems by receding horizon control via discrete-time approximations
This thesis is a systematic presentation of our results in the field of stabilization of sampled data nonlinear systems by receding horizon control. The results presented in the thesis were published in [17], [18], [19], [20], [21], [22], [23], [41] and [42]. The research reported in this thesis was carried out at the Budapest University of Technology and Economics, Mathematical Institute, Depa...
متن کاملAsymptotic stabilization of dynamically quantized nonlinear systems in feedforward form
This paper studies the stabilizability of an n-dimensional quantized feedforward nonlinear system. The state of that system is first quantized into a finite number of bits, and then sent through a digital network to the controller. We want to minimize the number of transmitted bits subject to maintaining asymptotic stability. In the prior literature, n bits are used to stabilize the n-dimension...
