Disturbance rejection for a rotating flexible spacecraft: a port-Hamiltonian approach

Autor: Denis Matignon, Flávio Luiz Cardoso-Ribeiro, Said Aoues, Daniel Alazard

Publikováno v: IFAC-PapersOnLine. 51:113-118

In this paper, the mathematical model of a flexible spacecraft system composed of a hub and two symmetrical beams loaded with tip masses is reconsidered to design a control law for internal disturbance rejection. This model has a port-Hamiltonian str

Modeling and Control of a Rotating Flexible Spacecraft: A Port-Hamiltonian Approach

Autor: Said Aoues, Daniel Alazard, Denis Matignon, Flávio Luiz Cardoso-Ribeiro

Publikováno v: IEEE Transactions on Control Systems Technology.

In this brief, we develop a mathematical model of a flexible spacecraft system composed of a hub and two symmetrical beams using the port-Hamiltonian framework. This class of system has favorable properties, such as passivity for controller synthesis

Control of a flexible spacecraft using discrete IDA-PBC design

Autor: Said Aoues, Denis Matignon, Daniel Alazard

Publikováno v: IFAC-PapersOnLine. 48:188-193

This paper has two objectives, first synthesize a discrete-time IDA-PBC for an underactuated port-Hamiltonian system, and second stabilize the angular position of an experimental testbed used in aerospace engineering. Based on the energetic integrato
