摘要：

This paper proposes a high-performance speed measurement method for electric drives using incremental encoders. The proposed solution improves the period-based speed estimation method. Such methods suffer from low resolution of time measurement at high speeds. The proposed method solves this problem by processing every speed estimation between the consecutive execution of the speed controller predicting the speed signal in order to achieve maximum performance of the speed loop. The processing algorithm was suggested for the speed estimation. The new method was studied and compared with conventional methods with the modelling experiment. It shows a good step response transient with lower oscillation in comparison to conventional methods for the same tuning of the speed controller.
