Abstract
An approach to attenuate the brake judder actively is proposed. The proposed judder compensation algorithm generates a clamp force command that attenuates the judder inducing brake torque variation. An electromechanical brake with high-bandwidth closed-loop clamp force tracking performance is utilised to follow the generated command, where the judder is compensated at its source. Experimental results are presented and the compensator is validated over fixed and varying wheel speeds with significant judder attenuation demonstrated.
