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.Index Terms - Brake-by-wire closed-loop control eddy current,,,Machine electromagnetic torque, model nonlinear steady, state.Model parameter, estimation.
