A position controller for motors for increasing the position loop gain of a full-close control system without causing recurrence of vibration. The controller where a position signal representing the position of a movable table and outputted from straight-line motion position sensing means attached to a straight-line motion mechanism is used as a position feedback signal comprises differentiating means (2) for differentiating a straight-line motion position signal and outputting a straight-line motion speed signal, subtracting means (4) for calculating the difference between a speed command signal and the straight-line motion speed signal, integrating means (3) for integrating a difference signal outputted form the subtracting means, proportional gain means (1) for receiving the output signal from the integrating means, and adding means (19) for adding the output signal form the proportional gain means to the speed command signal and outputting a new speed command Vr.
A position controller for a motor where a straight-line motion position signal representing the position of a movable table and outputted from a straight-line motion position sensing means attached to a straight-line motion mechanism is used as a position feedback signal comprising:
A position controller for a motor where speed control is performed based on a speed signal obtained by differentiating a rotational position signal of the motor and also position, control is performed based on a loading position signal from a position sensor attached to a load riven by the motor comprising:
A position controller for a motor where speed control is performed based on a speed signal obtained by differentiating a rotational position signal of the motor and also position control is performed based on a loading position signal from a position sensor attached to a load driven by the motor comprising:
