摘要: A sinusoidal signal is superimposed on a current command value of q-axis (torque shaft) supplied from host, and according to the resulting value, output voltage power converter controlled. For calculation added q-axis, with use ripple component information induced coefficients d-axis rotating coordinate system permanent magnet motor, values an average d-axis, inductance calculated above-described q-axis.
