State Feedback Robust Controller for Ship Track-keeping
نویسندگان
چکیده
In the paper the problem of ship trajectory tracking with ε-accuracy is considered. A three-degrees-of-freedom ship model with full dynamic interaction between motions in roll, sway and yaw is assumed. The aim of the paper is to determine the robust control for ship trajectory tracking with ε-accuracy. Such control is obtained by means of a state feedback (called Tytus feedback) system characterised by an arbitrarily large gain. For this purpose a non-linear as well as linearised stable and unstable ship model is used. The simulation results confirm that a high precision performance can be achieved by the proposed control scheme. Copyright © 2002 IFAC

In this paper, first a new algorithm for pole assignment of closed-loop multi-variable controllable systems in a prescribed region of the z-plane is presented. Then, robust state feedback controllers are designed by implementing a neural fuzzy system for the placement of closed-loop poles of a controllable system in a prescribed region in the left-hand side of z-plane. A new method based on the...

This paper studies the design of a robust output feedback controller subject to actuator saturation. For this purpose, a robust high-gain sliding mode observer is used to estimate the state variables. Moreover, the combination of Composite Nonlinear Feedback (CNF) and Integral Sliding Mode (ISM) controllers are used for robust output tracking. This controller consists of two parts, the CNF part...
متن کاملRobust H_∞ Controller design based on Generalized Dynamic Observer for Uncertain Singular system with Disturbance
This paper presents a robust ∞_H controller design, based on a generalized dynamic observer for uncertain singular systems in the presence of disturbance. The controller guarantees that the closed loop system be admissible. The main advantage of this method is that the uncertainty can be found in the system, the input and the output matrices. Also the generalized dynamic observer is used to est...
