Abstract

PURPOSE:To improve the accuracy of locus by correcting the position targeted value of each spindle based on the prediction value of the central angle of the circular arc and that of the square of the deviation of the central angle of the circular arc to obtain the same result as the negation of disturbance added in the radius direction of a circular arc. CONSTITUTION:The central angle theta0 of a targeted circular arc and the radius r0 of a targeted circular arc locus 5 are calculated from the position targeted value supplied to each spindle, and the central angle theta of the circular arc and the deviation DELTAtheta of the central angle of the circular arc at a circular arc locus 6 are estimated from the control characteristic of the central angle of the targeted circular arc and a calculated central angle theta of the targeted circular arc. And a vector proportional to the product of the square of the deviation DELTAtheta of the central angle of the circular arc whose size is estimated and the radius r0 of the targeted circular arc locus 5 in a direction advancing to the central angle theta of the circular arc estimated from the rotational center of the circular arc locus 6, and each axial component of the vector is added on the position targeted value of each shaft as a correction quantity. In such a way, it is possible to reduce the locus error of the circular arc locus by eliminating the influence of the disturbance without changing a position control system.
