<p>PURPOSE:To obtain excellent travelling performance even on the travelling of both tracks of a straight line and a curve by using a position regulator as a P regulator on travelling on the straight line and employing the position regulator as a PI regulator on travelling on the curve. CONSTITUTION:A position regulator 9 outputs a deviation signal DELTAN* between a position detecting signal x0 and a position set value x*. A speed regulator 6 outputs a current set point I* corresponding to a deviation between a signal acquired by adding the deviation signal DELTAN* and a speed set point N*0 and a speed detecting value. A current regulator 5 controls a power converter 4 in response to a deviation between the current set point I* and a current detecting value. A switch 95 is short-circuited and the position regulator 9 is used as a P regulator on travelling on a straight line, and the switch 95 is opened and the position regulator 9 is employed as a PI regulator on travelling on a curve.</p> |
