The measurement accuracy of GMR Current sensors suffers under the influence of hysteresis. For solving this problem, a hysteresis model has been implemented to keep track in real time of the sensor output signal. The model is a simplified version of the T(x) hysteresis model. Very good results have been achieved in comparing the software simulations and the real sensor characteristics. The model has been further implemented on a fixed-point Digital Signal Controller (DSC), connected to the sensor output. The linear output of the DSC confirmed the functioning of the model in the hardware implementation. An algorithm for eliminating error propagation during the measurements has been also developed.
