Abstract
A processing unit for effecting speed control in a drive control apparatus includes a storing unit having a first table which stores discrete values having exponential intervals, and a second table which stores multiples of normalized reference values having uniform intervals from each other and relating to a distance between a driven body subject to the speed control and a target position. The discrete values lie in a range over which the normalized reference values vary and are bound in a predetermined relation to a coefficient multiplied by the normalized reference values. The normalized reference values lie in the upper 1/2 range of said discrete values. A control target value generating unit calculates a control target value relating to a target speed of the driven body, by referring to the first and second tables.
