ACCELERATION/DECELERATION CONTROL DEVICE |
摘要 |
A residual-velocity calculating unit calculates a residual velocity that corresponds to a velocity increment when an acceleration is reduced from a current command acceleration to zero according to an acceleration reduction curve. A differential-velocity calculating unit calculates a differential velocity vs=v0-vn, which is a difference between a target velocity v0 and a current velocity command for every command generation period. An acceleration-reduction-start-timing determining unit compares the residual velocity to the differential velocity for determining whether acceleration reduction starts. When a condition that the residual velocity is equal to or larger than the differential velocity is satisfied, the acceleration-reduction-start-timing determining unit determines the start of the acceleration reduction and starts to reduce the command acceleration according to the acceleration reduction curve generated by the command generating unit.
