VECTOR CONTROL SYSTEM OF INDUCTION MOTOR |
摘要 |
PURPOSE:To enable to control to always perpendicularly cross a magnetic flux to the secondary current including the interference variation due to the angular frequency of a power source by correcting to cancel the mutual interference due to the primary current. CONSTITUTION:A correction calculator 3 calculates the correction value for correcting the interference due to alpha-phase primary current i1alpha to the value passed through a coefficient unit 31 of the primary resistor r1 to alpha-phase primary current set value i*alpha to control the secondary magnetic flux lambda2 constantly for setting the beta-phase primary voltage e1beta. Further, it adds a correcting value for correcting the interference due to the beta-phase primary current i*1beta to the value passed through a coefficient unit 35 of the primary resistor r1 to the set value i*1alpha for setting the alpha-phase primary voltage e1. Thus, the motor 1 can be controlled for speed and torque in noninterference between the magnetic flux and the secondary current. |
