The invention relates to a control device for synchronizing a plurality of driving units, the speed thereof controlled by a time-variable desired signal which is common for all units. For each driving unit a positional control means in combination with a speed control means is provided. The positional control means receives a signal for the desired position of the correlated driving unit which signal is produced in an integrating means from the desired speed signal and further receives a signal representing the actual position of the unit. The output signal of the speed control means is added to the desired speed signal modified in an amplifying network. The gain control of the amplifying network is selected such that the transient response of the compensating means is inversely proportional to the transient response of the actuating means and the drive unit. This allows for a high synchronizing accuracy. |
