Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/171233
Kind Code:
A1
Abstract:
Even given periodically steep changes in a command value (id*, iq*), which is the target value of a compensating current (Ic), this control device allows the voltage command value (Vid, Viq), and by extension the compensating current (Ic), to follow said periodically steep changes with good responsiveness. Deviation processing units (714, 715) perform proportional integral control of the deviation (Δid, Δiq), respectively, and output the values (ido, iqo). Repetitive controllers (716, 717) perform repetitive control on the values (ido, iqo) and output values (idr1, iqr1). An adder (718) adds the value (ido) and the value (idr1) to generate a voltage command value (Cid). An adder (719) adds the value (iqo) and the value (iqr1) to generate a voltage command value (Viq).
