METHOD AND DEVICE FOR THE DECENTRALISED OPERATION OR CONSTRUCTION OF A PRECISE ANGLE SYNCHRO-CONTROL SYSTEM IN A MULTI-MOTOR DRIVE SYSTEM

摘要

The invention relates to a method for the decentralised operation of a device for controlling the precise angle synchronism of individual drive mechanisms of a multi-motor drive system linked by a synchronisation bus (4). According to the invention, the set values are processed in such a way that a single drive control device (1) only requires non-time-critical set values. Consequently, the higher-ranking control system available (5) does not have to fulfil any special requirements relating to speed and synchronisation. The control indicator (12) is set statistically and dynamically by means of the control signal (Sw), in such a way that the synchro-controlled drive mechanism can be synchronised at any reference point which is predetermined by means of the set angle value (ws), or can be positioned at said reference point. The drive mechanism can be given a speed relation (r). The position of said drive mechanism can also be adjusted by a predetermined displacement angle (wv). The invention ensures that in the event that no machine set speed value (v*) is provided, each individual drive mechanism slows down in a synchro-controlled, synchronous manner.
