Abstract

PURPOSE:To control a load vibration caused by a gear backlash appropriately and surely by connecting non-linear elements of different characteristics with respective motors. CONSTITUTION:The deviation between a rotational speed command value nM' and a rotational speed actual value nM is inputted to obtain the output of a speed regulator 30, that is, a current command value ia, which is inputted to non-linear elements 40A, 40B of respectively different characteristics to form individual current command values ia1, ia2. Respective thyristor converters 24A, 24B are subjected to automatic control by said current command values ia1, ia2. As a result, because the polarity reversing positions of respective thyristor converters 24A, 24B differ from each other in the vicinity of the zero point, backlashes between gears 18 and 20A and between gears 18 and 20B are never synthesized when DC motors 10A, 10B rotate reversely. Therefore, the vibration of a load 14 can be controlled surely.
