PURPOSE:To minimize the loss of a driving motor when a shedding motion mechanism of a loom is driven with the driving motor for exclusive use. CONSTITUTION:The target extent of rotation (Po) for a driving motor (M) is outputted by a positional command part 10 according to an angle of rotation (theta) of a main shaft (A) in a loom. The extent (Pf) of rotation of the driving motor (M) is fed back by a positional control part 20 to sense the deviation (d). Thereby, the rotation of the driving motor (M) is controlled so as to cancel the deviation (d). A loop gain of a positional control loop (20c) is regulated based on the motional position of the control object by a gain correcting part 30. |
