Title:
DIGITAL CONTROLLER
Document Type and Number:
Japanese Patent JPH04205203
Kind Code:
A
Abstract:
PURPOSE:To minimize the detection delay time of a control system and to improve the detection accuracy by converting a detection signal in synchronism with the sampling time of a control system and outputting a synchronizing signal synchronized with the conversion to a control arithmetic means. CONSTITUTION:A rotational angle converter 121 converts the rotational angle signal 10a in synchronism with the sampling period of the control system and outputs digital rotational angle data 121a to the control arithmetic part 13. Further, the synchronizing signal 121b is outputted to the control arithmetic part 13, which starts a control arithmetic process with this synchronizing signal 121b. Thus, the synchronizing signal 121b for the sampling time is provided for the rotational angle converter 121, so variation in rotational angle data read time interval and an error from the sampling time originating from the performance limit of a microcomputer constituting the control arithmetic part 13 can be eliminated. Consequently, the detection delay time of the control system is minimized and the detection accuracy is improved.
