Control apparatus and control method for AC motor |
摘要 |
A control apparatus for an AC motor controls an inverter in a pulse width modulation scheme to feed a coil current to a stator coil of a stator. A pattern switching mechanism switches a control pattern to a first pattern or to a second pattern; a first pattern calculating mechanism calculates a control signal using a first pattern parameter; a second pattern calculating mechanism calculates a control signal using a second pattern parameter; an offset calculating mechanism calculates a difference between a control signal of an old pattern and a control signal of a new pattern, and reflects the offset amount on the control signals; and a control output mechanism calculates a final control output signal on the basis of the control signals, and transmits the final control output signal to the inverter. |
