| Outline of Final Research Achievements |
A position/speed sensorless control applicable to both parameter measurement and sensorless control for all adjustable speed ac motor drives have been studied, tentatively named Universal Sensorless Vector (USV) control. The versatility of the USV control was remarkably improved as follows. 1) A novel load angle estimation algorithm made it possible to apply the USV control to all induction and permanent magnet synchronous motors. This contributes to expanding the scope of application of the USV control. 2) A new method for tuning not only electrical motor parameters but also suitable flux-axis current command using an inverter for motor drive was shown. As a result, extra equipment required when classical parameter measurement methods are employed can be removed. The validity of the proposed method was demonstrated with experimental verification using ac motors in the laboratory.
