PURPOSE:To independently control torque components and magnetic flux components, and to realize the vector control of high performance by cancelling a mutual interference in a motor. CONSTITUTION:A regulator 3 for a component current iM contributing to a magnetic flux generation, a regulator 4 for a component iT contributing to a torque generation, and transfer function blocks (a)'-(k)' are provided. Here, the amounts calculated in accordance with motor constants,lSIGMA, M, n, a rotating speed omega2, a magnetic flux PSI0 and its change rate delta are so added and subtracted at the output stage of the regulators 3, 4 as shown by arrows of solid and broken lines so as to cancel the mutual interference in a motor. The results are as the voltage values e'T, e'M of the shafts. Thus, the currents iM and iT, i.e., the torque and the magnetic flux can be independently and hence controlled in a noninterference state. |
