Abstract
A track control apparatus includes an interpolation/acceleration and deceleration calculating unit that interpolates a commanded route and calculates a post-acceleration and deceleration interpolation route, an axis distributing unit that generates a position command for each movable axis from the post-acceleration and deceleration interpolation route, a servo-response calculating unit that calculates a servo response to the position command, a tangential-direction-servo-response calculating unit that obtains a tangential direction servo response from the post-acceleration and deceleration interpolation route, a reference-point generating unit that obtains a reference point from the tangential direction servo response, a position-vector correcting unit that corrects the position command for each movable axis to output a post-correction position command for each movable axis, and a servo control unit that outputs motor driving torque such that each movable axis follows the corresponding post-correction position command.
