Abstract
Current sensor errors affect torque control and saliency-tracking position estimation of ac machines. A spatial model of current sensor gain deviation is developed and used to determine its affect on a general current measurement, verified with experimental data. Three current sensors enable a three-phase three-wire system to compensate for current sensor gain deviation independent of additional machine saliencies. Simulation and experimental results confirm the current sensor gain deviation compensation algorithm.
