Title:
複数の主駆動モータを備えた印刷機の制御
Document Type and Number:
Japanese Patent JP7203827
Kind Code:
B2
Abstract:
The invention relates to the control of printing presses, in particular sheet-fed presses, having a plurality of main drive motors (M), which are connected by means of a drive train. In order to control a press rotational speed, a central control unit (ZR) is used, wherein in particular current rotational speeds of different positions of the drive train are used for the control, the rotational speeds being sensed by sensors (S) or estimated by observers. A rotational speed variable, which can be derived from a momentum equation, and/or one or more torque differences, which can be selected from the differences between the feed-in torques of the motors, are/is used as a controlled variable. The torque differences are selected in such a way that the lifting off of tooth flanks in the drive train is counteracted or prevented. A PI multi-variable controller is used as the controller structure; the controller structure can be simplified by means of an input coupling in such a way that a fixed or variable torque distribution is realized. The guidance behavior and disturbance behavior can be handled separately. The controller parameters are obtained by the optimization of a system standard, the system to be optimized having positions of important sources of disturbance as system inputs and the angle differences relevant to the printing quality as system outputs. For the positioning of the drive motors, the eigenmodes of the drive train and the positions of important sources of disturbance are used, wherein for the active torsional vibration damping the drive motors are preferably in the edge positions in the last and/or in the first module, and/or in the turning module.
