Abstract
A servo control system capable of using an angle-based synchronization learning control, even when a reference position is not given, while maintaining the advantage of the angle-based synchronization method. The servo control system has X-, y- and z-axes servo controllers, each configured to control x-, y- and z-axes servomotors, respectively. Each of x- and y-axes servo controllers has a reference signal generating part configured to generate a reference signal which monotonically increases or varies in one direction, based on the position command of each axis transmitted from a higher-level controller.
