  • Publication number: 20170108038
    Abstract: A control device (101) for controlling a magnetic levitation system includes a controller (103) for controlling one or more voltages directed to one or more windings of the magnetic levitation system on the basis of a deviation of a position of an object (108) to be levitated from a reference position so as to control a resultant magnetic force directed to the object. The controller selects, for each of temporally successive control periods, a control direction so that ability of the resultant magnetic force to decrease the deviation of the position is improved when the resultant magnetic force is changed in the selected control direction. Thereafter, the one or more voltages are selected in accordance with the selected control direction so as to decrease the deviation of the position by changing the resultant magnetic force. Thus, there is no need for nested control loops which are typically challenging to tune.

    Abstract: A fluid type power transmission device in which a torque transmission path for transmitting torque from a vehicular engine is provided with a dynamic damper mechanism formed by disposing a plurality of damper springs between an inertial rotating body and a rotation-transmitting member forming part of the torque transmission path. An elastic member always linked to one of the rotation-transmitting member and the inertial rotating body is added to the dynamic damper mechanism. Play occurs in a torque direction between the elastic member and the other of the rotation-transmitting member and the inertial rotating body at a time of low speed rotation, but the elastic member exhibits resilient force between the rotation-transmitting member and the inertial rotating body in response to deformation due to centrifugal force at a time of high speed rotation that is a predetermined rotational speed or greater.
