Abstract
A servo system generates a velocity profile for moving a load from one position to another by dividing the time during which the load is moving into a plurality of segments, each segment being one half as long as the preceding segment. For each segment a fixed number of desired velocity values are stored and used to control the velocity of the moving load. This results in increasing resolution of the velocity wave as the load approaches its desired position, while not requiring excessive storage capacity for storing the desired velocity values.
