Popis:	In the first report, the authors described the mechanical structure of a friction drive system used in this study and the traction characteristics acted between the pinion roller and the slider. Since it became clear by the first report that the traction T had the maximum value Tmax, the acceleration of the slider Vs had also the maximum value Vsmax which was obtained from the dynamic equation in this system. So, when the acceleration of the slider Vs is kept at Vsmax, the trapezoidal velocity control is very effective for the friction drive. The authors discuss the effects of 3 kinds of trapezoidal velocity control ((1) almost without slip between the pinion roller and the slider, (2) with slip and (3) with slip and with integral regulator during deceleration). As a result, it becomes clear that the control of (3) shows the shortest settling time when the slider reaches within 1μm from the desired position.
