Velocity Observer Design for Tether Deployment in Hamiltonian Framework
AerospaceThis paper presents a nonlinear velocity observer of tether deployment using the immersion and invariance technique, and the velocity observer design problem is recast as a problem of designing an attractive and invariant manifold inside the Hamiltonian ...

Event-triggered Control of Port-Hamiltonian Systems under Time-delay Communication [PDF]
arXiv, 2022 We study the problem of periodic event-triggered control of interconnected port-Hamiltonian systems subject to time-varying delays in their communication. In particular, we design a threshold parameter for the event-triggering condition, a sampling period, and a maximum allowable delay such that interconnected port-Hamiltonian control systems with ...

Hamiltonian-based algorithm for relaxed optimal control [PDF]
IEEE Conference on Decision and Control, 2016 This paper concerns a first-order algorithmic technique for a class of optimal control problems defined on switched-mode hybrid systems. The salient feature of the algorithm is that it avoids the computation of Fréchet or Gâteaux derivatives of the ...

Optimization Provenance of Whiplash Compensation for Flexible Space Robotics
Aerospace, 2019 Automatic controls refer to the application of control theory to regulate systems or processes without human intervention, and the notion is often usefully applied to space applications.

The cost optimal control system based on the Kermack–Mckendrick worm propagation model
Journal of Algorithms & Computational Technology, 2016 Although the network worm propagation models are able to predict trends in the spread of the worm, these papers did not consider the economic losses caused by the worm propagation.

EPHS: A Port-Hamiltonian Modelling Language [PDF]
arXiv, 2022 A prevalent theme throughout science and engineering is the ongoing paradigm shift away from isolated systems towards open and interconnected systems. Port-Hamiltonian theory developed as a synthesis of geometric mechanics and network theory. The possibility to model complex multiphysical systems via interconnection of simpler components is often ...

Robust PI passivity-based control of nonlinear systems: Application to port-Hamiltonian systems and temperature regulation [PDF]
American Control Conference, 2015 This paper deals with the problem of control of partially known nonlinear systems, which have an open-loop stable equilibrium, but we would like to add a PI controller to regulate its behavior around another operating point.
