Journal ArticleDOI
Wheel Slip Control of EVs Based on Sliding Mode Technique With Conditional Integrators
TL;DR: A new control system, based on field programmable gate array technology, targeting the powertrain control of multi-motor electric vehicles (EVs), and demonstrates a good slip regulation and robustness to disturbances.
Journal ArticleDOI
Combined Sizing and Energy Management in EVs With Batteries and Supercapacitors
TL;DR: The results indicate that the filter-based approach, although simple and numerically efficient, generally requires an oversized storage unit and that, if the range requirements of the EV are not very high, the use of SCs enables energy savings of up to 7.8%.
Journal ArticleDOI
Torque blending and wheel slip control in EVs with in-wheel motors
TL;DR: In this paper, the anti-lock braking system (ABS) is designed for in-wheel electric vehicles, which is composed of a tyre slip controller, a wheel torque allocator and a braking supervisor.
Journal ArticleDOI

TL;DR: The DS vocalic anatomical functional ratio represents the main distinctive parameter between the two groups studied, and it may be useful in conducting assessments.
Journal ArticleDOI
Speech technologies for blind and low vision persons
TL;DR: In this work a review of speech technologies and their applications that provide or augment access to the printed or electronic information, the daily or social activities, as well as the private or public facilities for blind or low vision persons is presented.
