An Approch for the Emulation of DC Grid Admittances: Implementation an a Buck Converter

Drazen Dujic, Francisco Daniel Freijedo Fernández, Enrique Rodriguez Diaz

This work proposes a method to actively emulate dc grids, including their equivalent admittance, by means of a modified current control structure of a dc/dc converter. The stability of power converter units (PCUs), interconnected with electrical grids is f ...

Predictive control of spiral vortex breakdown

François Avellan, François Gallaire, Simon Pasche

The predictive control of the self-sustained single spiral vortex breakdown mode is addressed in the three-dimensional flow geometry of Ruith et al. (2003) for a constant swirl number S = 1.095. Based on adjoint optimization algorithms, two different contr ...

A design method for distributed luenberger observers

Colin Neil Jones, Francisco Fernandes Castro Rego

The paper addresses the problem of designing distributed observers for discrete linear time-invariant (LTI) systems with distributed sensor nodes subjected to bounded measurement noise. A solution is proposed in terms of a distributed LTI Luenberger observ ...

Scalable closed-form trajectories for periodic and non-periodic human-like walking

Auke Ijspeert, Salman Faraji

We present a new framework to generate human-like lower-limb trajectories in periodic and non-periodic walking conditions. In our method, walking dynamics is encoded in 3LP, a linear simplified model composed of three pendulums to model falling, swing and ...

Trajectory Optimization Through Contacts and Automatic Gait Discovery for Quadrupeds

Jonas Buchli, Farbod Farshidian, Alexander Winkler

In this letter, we present a trajectory optimization framework for whole-body motion planning through contacts. We demonstrate how the proposed approach can be applied to automatically discover different gaits and dynamic motions on a quadruped robot. In c ...

A survey on tactical control algorithms for path tracking unmanned surface vehicles

Murat Kumru

In this study, a survey on control allocation algorithms in tactical level control for path tracking unmanned surface vehicles (USV) is conducted. The strategic goal in the path tracking problem is to assist navigation solution of an unmanned underwater ve ...

Medium Voltage DC-DC Converter for Power Collection Links

Gina Kristin Steinke

Nowadays electrical energy generation is an important topic discussed in the society. Since technologies like wind or solar energy generation are most of the time placed far away from the city centres one point to focus on is the transmission of the energy ...

Controlling the Topological Sector of Magnetic Solitons in Exfoliated Cr1/3NbS2 Crystals

Frédéric Mila, Natalia Chepiga, Fengping Li

We investigate manifestations of topological order in monoaxial helimagnet Cr1/3NbS2 by performing transport measurements on ultrathin crystals. Upon sweeping the magnetic field perpendicularly to the helical axis, crystals thicker than one helix pitch (48 ...

Device for Determining a Bidirectional Reflectance Distribution Function of a Subject

Martin Vetterli, Loïc Arnaud Baboulaz, Gaël Georges Soudan

The present invention relates to a device (10) for determining a bidirectional reflectance distribution function of a subject (S) comprising: a light source (LS) for producing an incident light (li) and directing said incident light (li) onto a subject (S) ...

On convergence and performance certification of a continuous-time economic model predictive control scheme with time-varying performance index

Colin Neil Jones, Andrea Alessandretti

This paper addresses the design of convergence and performance certified sampled-data model predictive control (MPC) laws with a time-dependent economic performance index. More precisely, using a dissipativity property of the system, we provide a set of su ...
