A sliding mode controller based on a polynomial-based eddy current machine model is presented. The controller provides a novel torque tracking control strategy that does not require any torque measurement. The enhanced parametric model captures the steady-state torque-speed-current characteristics of the eddy current machine. The model parameters are experimentally estimated using a two stage least square type algorithm. No look-up table is required for the proposed sliding mode controller once the model parameters have been identified. Simulation of the proposed controller using a SIMULINK model incorporating the controller model, the eddy current brake model and a 14 degree of freedom vehicle model is performed. Simulation results are presented for the proposed controller in the context of an automobile braking application. The simulation results show good torque tracking performance of the proposed controller. The method can be applied in an eddy current machine based brake-by-wire system.
