Abstract:

Suppression of vibration of a load machine without reducing the responsiveness of the load machine to an operation command is achieved by a method and an apparatus for controlling an inertial system intended to control an inertial system that has a motive power generator and a load machine that are coupled to each other via a torque transmission element. Acceleration command information that designates the acceleration of the load machine is multiplied by a predetermined gain to produce a vibration suppression control variable. The vibration suppression control variable is added to the position command to form a vibration suppression control command, and the inertial system is controlled according to the vibration suppression control command.
