Abstract

An enhanced polynomial-based parametric model of an eddy current electric machine for automotive braking applications has been introduced in this paper. The parametric model captures the steady state torque-speed-current characteristics of the eddy current brake. A two-stage estimation process has been introduced to identify the coefficients of the retarder model from experimental data through a least square type algorithm. The model is then validated via on-vehicle test data. A controller to generate eddy current machine command can be designed using the proposed parametric model which could be computationally more efficient.
