PURPOSE:To change speed smoothly, to simplify a circuit and to standerdize a servocontrol system by finding a speed correction signal on the basis of a position detecting signal while referring a speed list for position control in a positioning apparatus for the servocontrol system. CONSTITUTION:A position detecting signal (b) of an object to be controlled and clock information (c) from a timer 16 are inputted to a data processor 11, voltage difference DELTAe or -DELTAe from the ''0'' level at the value of the position detecting signal (b) and a speed correction signal (a) corresponding to the error DELTAx or -DELTAx of the stop position corresponding to the voltage difference is outputted while referring a speed list for position correction. Since a position error from a position to be stopped can be controlled while watching the value of the position detecting signal, the position can be controlled so that the object 14 to be controlled stops at the position to be stopped as accurately as possible. |
