Abstract
In a system for controlling a synchronous drive system suitable for use in a machining center of the type comprising a first and second servosystems wherein it is necessary to cause the outputs of the first and second servosystems to coincide with each other, there are provided a target setter for supplying a target value to the first and second servosystems, a compensation system inputted with the difference between the outputs of the first and second servosystems, and circuit means for inputting the output of the compensation system to the second servosystem. The compensation system is constituted by one, two or three of a proportionality element, a differentiating element, and an integrating element.
