Abstract

PURPOSE: To presume the unknown factors in the model based on the found data by using the model investigated logically as well as the damping phenomenon and then to give the suited correction to the subsequent control.
CONSTITUTION: The tip and the velocity of the subject put on roller stage 1 are detected through 4W4B. Friction coefficient μ1 and μ2 of the damping/nondamping time which are decided through the pre-trial are memorized 11 along with μ1 which is being corrected, and the latest μ1 and fixed μ2 are given to calculating device 13. The stop position of each subject is decided 12 based on the subject length and the stop mode and then delivered to device 13. Then the expected subject pass time is obtained between detection devices and then memorized 15 through calculation 13 based on penetration velocity μ1 and μO plus the desired stop position. At the same time, the input is given to damping control device 14, and damping device 3 is controlled and driven via the penetration velocity. The necessary pass time ta is obtained actually between the detection devices to give correction 16 to μ1 used according to the difference with the expected time. In this way, the optimum start timing can be given to the damping device.
