The switching point of combined flux observer had a very important influence on the performance of observer. An analysis to the relationship among the switching point, system parameters and performance of the observer was made, and the optimal design method of switching point was given. As the optimal switching point would change as the system parameters changed, it caused a decline in performance of combined flux observer. For this problem, a method of switch point self-tuning was proposed. Combined with the optimal design method of switch point, the switch point of combined flux observer could be real-time online adjusted which improved the performance and accuracy of combined flux observer.
