MOTOR DRIVING SYSTEM

In this motor driving apparatus 120, a phase compensation amount calculation unit 110 calculates a phase compensation amount Δθ for compensating a voltage phase θv* when a control mode is switched in a control selection unit 90. The control selection unit 90 outputs a 3-phase voltage command Vuvw* a...

Beschreibung
Zusammenfassung:	In this motor driving apparatus 120, a phase compensation amount calculation unit 110 calculates a phase compensation amount Δθ for compensating a voltage phase θv* when a control mode is switched in a control selection unit 90. The control selection unit 90 outputs a 3-phase voltage command Vuvw* according to a control mode among a plurality of control modes on the basis of a modulation rate Kh, the voltage phase θv, and the phase compensation amount Δθ. A PWM control unit 100 outputs gate signals Gun, Gup, Gvn, Gvp, Gwn, and Gwv on the basis of the 3-phase voltage command Vuvw* and a rotor position θd. An inverter 20 has a plurality of switching elements and drives an AC motor 10 by controlling the plurality of switching elements on the basis of the gate signals Gun, Gup, Gvn, Gvp, Gwn, and Gwv.
