SYSTEM OF ASYNCHRONOUS MOTOR SPEED VECTOR CONTROL

摘要

FIELD: electricity. ^ SUBSTANCE: structure of a control system in a vector control system includes a module of electromotive force and cross links calculation and a module to calculate extreme values of stator current components connected to control circuits of an active component of the stator current and control circuits of a magnetising component of the stator current accordingly as specified in the application materials. ^ EFFECT: improved dynamic and statistical characteristics of asynchronous motor in a wide range of speed control with simultaneous maintenance of maximum and constant efficiency factor of the motor in the whole permissible range of a load torque variation at the specified angular speed. ^ 4 dwg
