Title:
CONTROL METHOD FOR OSCILLATION SUPPRESSION OF PERMANENT MAGNET ASSISTED SYNCHRONOUS RELUCTANCE MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/134769
Kind Code:
A1
Abstract:
The present disclosure relates to a method for suppressing motor oscillation in an urban rail permanent magnet traction transmission system, in particular to an active damping compensation method in oscillation suppression, and in particular to a control method for oscillation suppression of a permanent magnet assisted synchronous reluctance motor, for use in solving the technical problem in the background art. According to the present disclosure, the technical problem of direct-current side oscillation caused by impedance mismatch of an urban rail permanent magnet traction system is solved on the basis of an original vector control method of the permanent magnet assisted synchronous reluctance motor, in combination with a voltage q-axis active damping compensation method, a voltage d-axis active damping compensation method, a current q-axis active damping compensation method, a current d-axis active damping compensation method, a torque active damping compensation method, and a modulation change method, such that the stability of the urban rail permanent magnet traction system under the control of the original vector control method is improved, and the hardware cost of the system is not increased while implementing the stability of the system.
