Title:
POSITIONING DEVICE
Document Type and Number:
Japanese Patent JPH04242407
Kind Code:
A
Abstract:
PURPOSE:To realize positioning arithmetic by an inexpensive CPU, etc., under an acceleration/deceleration characteristic which applies a small shook to a device in the positioning device which perform servocontrol for moving the driving position of a driving device from a certain position to another position. CONSTITUTION:A position command part 201 consists of a linear acceleration/ deceleration position command part 202 and a low-pass filter 203. The differential waveform of the output x1 of the part 202 has a polygonal-lined acceleration/deceleration characteristic and the output x1 is filtered by the filter 203 to obtain an output x2 having an acceleration/deceleration characteristic which varies smoothly in differential waveform, and this is supplied as a position command value (x) to a position control part. Thus, the shock applied to the driving device can be absorbed and a system which generates no error in the stop position of the device can be realized with simple circuit constitution.
