IPC: H02P27/16
Filed: 1990-09-18
Abstract: PURPOSE:To obtain a high-performance controller for synchronous motor which is stable even in a high driving frequency domain or under a heavy load by finding a reference voltage value on a dq axis by comparing the calculated reference current value on the dq axis with a detected value and transforming the reference voltage value into a three-phase armature winding shaft by means of a coordinate transformer.

A magnetic flux computing element 6 calculates an armature magnetic flux from the calculated detected current value and a detected field current value. A command is given so that a torque amount current can intersect the calculated magnetic flux at right angles. A calculated reference current value is compared with the a detected value and outputted as a reference voltage values vd and vq of the dq axis by means of an amplifier 9. The reference voltage values are given to a coordinate transformer 14 and threephase winding voltages vu, vv, and vw are further obtained from the voltage reference values and the output of the position computing element 5. These values become an AC quantity which varies depending upon a rotational electrical angular frequency.
