Abstract: The stator flux oriented vector control strategy was studied for electrically excited synchronous motor to satisfy the high performance of rolling mill main drive. A mixed stator flux observer was used to satisfy the full speed range. The mix observer includes a current-model which is used at low speed and a novel voltage-model which is used at high speed based on speed compensated. To improve the speed dy-namitic performance, the low order load observer for feed-forward torque current control was proposed in which fuzzy adaptive control was adopted. Simulation and experiment results demonstrate the strategy is effective.
