Abstract: This paper deals with a control technique of eliminating the transient vibration generated in a dies-driving spindle of a form rolling machine. This technique is based on a model-based control with a rotational speed sensor. A rotational speed sensor is installed in a driven gear part. A control model is composed of a reduced-order mechanical model. The performance of this vibration suppression control method in the velocity control loop is examined by simulations and experiments. Further, the effectiveness of the model-based control integrated into the position control loop is verified by simulations. Simulations and experiments show satisfactory control results.

Keywords: form rolling machines; dies-driving spindles; bull gear; velocity control loop; position control loop; model-based control; rotational speed sensors; transfer function; transient vibration; vibration suppression control.
