Assessment and preliminary design of an energy buffer for regenerative braking in electric vehicles [PDF]

open access: yes
Energy buffer systems, capable of storing the vehicle energy during braking and reusing this stored energy during acceleration, were examined. Some of these buffer systems when incorporated in an electric vehicle would result in an improvement in the ...

Synchronous response modelling and control of an annular momentum control device [PDF]

open access: yes
Research on the synchronous response modelling and control of an advanced Annular Momentun Control Device (AMCD) used to control the attitude of a spacecraft is described. For the flexible rotor AMCD, two sources of synchronous vibrations were identified.
