Abstract

PURPOSE:To reduce the lowering of a speed at the time of an impact load, by adding an offset value to a speed loop integrating term when a speed devia tion comes to a given value or more. CONSTITUTION:By a PI control circuit 11, a deviation between speed command signal omegar* and speed detection signal omegar is proportionally integrated, and via a limiter circuit 12, the output of exciting current component iqs is generated. Besides, by a secondary magnetic flux pattern generating circuit 13, from the speed detection signal omegar, arithmetic is performed on secondary magnetic flux phi2, and via a primary delay element 14, the output of secondary magnetic flux command phi2* is generated. Besides, by an exciting component current arithmetic circuit 16, from a mutual reactance M found through the secondary magnetic flux phi2 and the secondary magnetic flux phi2, the output of exciting component current command ids is generated. Then, according to the signal iqs, ids, phi2*, the output of the amplitude¦I1¦ of primary current command, angular frequency omega0, and a phase angle theta is generated. In the meantime, when a speed deviation omegar comes to a specified value or more, then an offset value is added to the output of the PI control circuit 11.
