Title:
POSITION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPS6057417
Kind Code:
A
Abstract:
PURPOSE:To perform the accurate positioning in a short time even with a long shift distance by carrying out the position control through the analog signal processing after having the same position control at a 1/4 pitch interval through the digital signal processing. CONSTITUTION:The 2nd and 3rd output signals delivered from a positioning sensor part 4 processed digitally at a digital signal processing part 100. Thus the shift and stop positions are controlled at a 1/4 pitch interval for the mobile part of a driver. After the position control is through with said mobile part, the 1st and 2nd output signals delivered from the part 4 are processed in an analog way to control the stop position of the mobile part of the driver within the 1/4 pitch interval. In such a way, the rough position control is carried out through the digital signal processing. Then the fine position control is performed through the analog signal processing. This ensures the accurate positioning in a short time despite a long shift distance.
