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 T_<max>, the acceleration of the slider V_s had also the maximum value V_<smax> which was obtained from the dynamic equation in this system. So, when the acceleration of the slider V_s is kept at V_<smax>, 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.
