Hybrid switching controller design for the maneuvering and transit of a training ship

Mirosław Tomera (2017)

International Journal of Applied Mathematics and Computer Science

Similarity:

The paper presents the design of a hybrid controller used to control the movement of a ship in different operating modes, thereby improving the performance of basic maneuvers. This task requires integrating several operating modes, such as maneuvering the ship at low speeds, steering the ship at different speeds in the course or along the trajectory, and stopping the ship on the route. These modes are executed by five component controllers switched on and off by the supervisor depending...

H control design for an adaptive optics system

Nikolaos Denis, Douglas Looze, Jim Huang, David Castañon (1999)

Kybernetika

Similarity:

In this paper we first present a full order H controller for a multi- input, multi-output (MIMO) adaptive optics system. We apply model reduction techniques to the full order H controller and demonstrate that the closed-loop (CL) system with the reduced order H controller achieves the same high level of performance. Upon closer examination of the structure of the reduced order H controller it is found that the dynamical behavior of the reduced order H controller can be accurately approximated...

Disturbance observer-based second order sliding mode attitude tracking control for flexible spacecraft

Chutiphon Pukdeboon, Anuchit Jitpattanakul (2017)

Kybernetika

Similarity:

This paper presents a composite controller that combines nonlinear disturbance observer and second order sliding mode controller for attitude tracking of flexible spacecraft. First, a new nonsingular sliding surface is introduced. Then, a second order sliding mode attitude controller is designed to achieve high-precision tracking performance. An extended state observer is also developed to estimate the total disturbance torque consisting of environmental disturbances, system uncertainties...
