Energy Saving Estimation of Athens Trolleybuses Considering Regenerative Braking and Improved Control Scheme

open access: yesResources, 2018
In this work, the electromechanical system of the 8000-series of Athens trolleybuses, based on data provided by OSY S.A., is analyzed. Those data were used to develop a valid model in order to estimate the total energy consumption of the vehicle under ...

Suppression of rotating machine shaft-line torsional vibrations by a driving asynchronous motor using two advanced control methods [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2023
Many industrial rotating machines driven by asynchronous motors are often affected by detrimental torsional vibrations. In this paper, a method of attenuation of torsional vibrations in such objects is proposed.
