TORQUE RIPPLE SUPPRESSING APPARATUS AND TORQUE RIPPLE SUPPRESSION METHOD |
摘要 |
PROBLEM TO BE SOLVED: To appropriately suppress torque ripples of a motor.SOLUTION: A signal calculation section 38 of a d-axis adjustment section 34 calculates an amplitude aof a cosine component and an amplitude bof a sine component of the Fourier series from a d-axis current signal iregarding a harmonic component of any order of the d-axis current signal i. A model learning section 40 generates a model signal Mfor removing ripple components from the d-axis current signal iby using a learning algorithm. A signal calculation section 42 of a q-axis adjustment section 36 calculates an amplitude aof a cosine component and an amplitude bof a sine component of the Fourier series from an angular acceleration signal φ. A model learning section 44 generates a model signal Mcorresponding to ripple components of the angular acceleration signal φof a q-axis current signal i. A d-axis current command value Iis superposed by the model signal Mand output. A q-axis current command value Iis superposed by the model signal Mand output.SELECTED DRAWING: Figure 1 |
