Dynamic system identification of Audi disc brake under anti-lock condition

Abstract

In this paper, a dynamic test of an Audi disc brake is performed on the JF-132 vehicle brake tester. The ARX model of the brake dynamics is developed. Based on measured data, model structure is determined, and the model parameter is identified employing the optical instrumental variable method. Through validation of residual whiteness and comparison of different observed data, the precision of the model is confirmed.
