<p>PURPOSE:To enable control to be performed wherein a responses to variations in both feeder supply quanity and screw rotational frequency are considered. CONSTITUTION:When inlet pressure of a gear pump is varied, a correction quantity-operating part 13 is operated, and a control input save time-operating part 15 operates control input save time T by a specific correction quantity which was operated. However, a feeder supply quantity correcting part 19 and a screw rotational. frequency correcting part 16 output respectively to a feeder driving part 11 and a screw driving part 4 based on the correction quantity obtained at the last time only during control input evacuation time T. Therefore, operated results based on the preceeding correction quantity and a next correction quantity are never supplied in a piled up state to a feeder or a screw, and the socalled hunting and excess control can be prevented.</p> |
