Title: Current control method for ac servomotor
Inventor: TOYOSAWA YUKIO
IPC: H02P23/18
Filed: 1994-12-26
Abstract: PURPOSE: To suppress a current increase in an AC servomotor during deceleration in a voltage saturation by using a d-phase current and decreasing a q-phase current command when a command voltage value is over a limit of a power amplifier. CONSTITUTION: A d-phase current in a direction of magnetic flux is calculated on the basis of d-q conversion of a driving current and a rotor phase, while the p-phase current is limited to zero under control. When a voltage saturation treatment block is in a voltage saturation state during deceleration, the result is fed to a q-phase current command compensation block 11 to compensate a q-phase current command. In the q-phase current command compensation block 11, a calculation is carried out according to the signal from the voltage saturation block, and a compensation value (Ic) is added to a q-phase current command (Iq*) to decrease the q-phase current command (Iq*) by using a d-phase current (Id). In this way, an increase in q-phase current can be reduced.
