Abstract
A servo system employs at least two multiple disk clutches arranged in series to each other in an axial direction and at least two pistons used for engagement and disengagement of the respective clutches and arranged to be nested each other so that one of the pistons fits inside the other. Also provided is a servo system control device with a piston-stroke order control section. The piston-stroke order control section determines a timing of operation of each of the pistons for engagement of the respective clutches so that the pistons are operated in a specified order that the outside piston is operated prior to the inside piston.
