Abstract
Eddy current brakes having advantages such as contactless operation, offer an alternative to conventional friction based brakes. The flux source in an eddy current brake can be produced by permanent-magnets or electrically excited windings. The former eliminates the need for an external supply, whereas the latter provides good control capability for the device. In order to take the advantages of both mentioned types, a hybrid electromagnetic brake has been introduced. One of the advantages of hybrid electromagnetic brake is the controllability of the brake system even when the hybrid electromagnetic brake is integrated in a vehicle. So, robust speed and slip control schemes for hybrid electromagnetic brake systems taking into account the brake and vehicle dynamics have been developed for uncertain system parameters, and unknown external disturbance conditions, owing to neural networks learning and adaptation abilities. These control schemes exhibit advantages such as not requiring exact information about the brake and vehicle parameters for the controller design, and that the control algorithm is capable of efficiently tracking performance while ensuring the stability of the closed-loop system. The controllers are suitable for many vehicle’s active safety control systems such as, adaptive cruise control, anti-lock braking systems, electronic stability control, rollover prevention, and autonomous vehicle operations.
