Title:
DOOR CONTROL DEVICE OF ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2010/106863
Kind Code:
A1
Abstract:
In a door control device of an elevator, a magnetic flux observation section (117) estimates the secondary magnetic flux of a door motor (5) using a primary voltage command values Vd*, Vq* and an arithmetic expression based on the mathematical model of the door motor (5). A magnetic flux control section (112) and a speed control section (119) generate respective current commands using the secondary magnetic flux of the door motor (5) calculated by the magnetic flux observation section (117).
