ROTATION ANGLE POSITIONING DEVICE |
摘要 |
In a rotation angle positioning device 6 including: a rotation angle detection device 7 which has a detection target ring 8 and an angle detection sensor 9; and a rotating-shaft driving device 10 rotating a rotating shaft so as to cause a rotation angle to become a given command valueαfor rotation angle, there are provided: an error pattern storage unit 11a storing a tooth-to-tooth period error pattern F made up of errors between detected rotation angles by the angle detection sensor 9 and actual rotation angles, corresponding to respective correction dividing points of an arbitrary tooth-to-tooth period in the detection target ring 8; and a command value correction unit 11b correcting the command valueαfor rotation angle based on the tooth-to-tooth period error pattern F to find a corrected command valueα2 for rotation angle.
