Catenary Voltage Support: Adopting Modern Locomotives With Active Line-Side Converters

Alfred Rufer, Behrooz Bahrani, Martin Aeberhard

This paper proposes a voltage support scheme for traction networks, which compensates for the voltage drop along the catenary line to which locomotives are connected. The proposed method is based on the injection of capacitive reactive power through the cu ...

Railway Catenary Parameters Identification based on Harmonic Current Injection

Alfred Rufer, Behrooz Bahrani, Martin Aeberhard

Modern trains with active line-side converters are currently the state-of-the-art technology in the traction industry. In such systems, the active line-side converter of the drive system can be exploited for power quality improvement purposes. In this pape ...

A musculoskeletal shoulder model based on pseudo-inverse and null-space optimization

Dominique Pioletti, Denis Gillet, Alexandre Terrier, Philippe Müllhaupt, Alain Farron, Yvan Michellod, Martin Aeberhard

The goal of the present work was assess the feasibility of using a pseudo-inverse and null-space optimization approach in the modeling of the shoulder biomechanics. The method was applied to a simplified musculoskeletal shoulder model. The mechanical syste ...

Dynamical biomechanical model of the shoulder: null space based optimization of the overactuated system

Dominique Pioletti, Denis Gillet, Alexandre Terrier, Philippe Müllhaupt, Yvan Michellod, Martin Aeberhard

A new dynamical model of the shoulder has been developed. It consists of eleven muscles. The glenohumeral joint, modeled as a spherical joint, allows three rotations and blocks the translations. Muscle wrapping around a spherical humeral head is calculated ...
