Torque controller for permanent magnet synchronous motor

When output voltage V 1 of an electric power converter reaches a prescribed voltage V 1 * ref , a difference between V 1 and V 1 * ref is integrated to correct a commanded torque Äo* (Ä* = Äo* + Ä*) . Accordingly, a vector controller for a permanent magnet synchronous motor 1 can achieve highly pre...

Beschreibung
Zusammenfassung:	When output voltage V 1 of an electric power converter reaches a prescribed voltage V 1 * ref , a difference between V 1 and V 1 * ref is integrated to correct a commanded torque Äo* (Ä* = Äo* + Ä*) . Accordingly, a vector controller for a permanent magnet synchronous motor 1 can achieve highly precise torque control at quick response even near a point at which the output voltage of the electric power converter 2 is limited (saturated). In addition, a vector controller, for a permanent magnet synchronous motor, that can be applied to both an inexpensive current detecting system and a system from which a position sensor is eliminated is provided.
