Abstract :
In order to overcome the defect of conventional pure integrator observer for stator flux linkage, a full-order state observer with robust pole assignment algorithms is proposed in this paper. The simulation results show that the full-order state observer can effectively overcome the pure integrator´ defect and can observe stator flux linkage accurately in DTC and DTC has better performances.
