Title:
DIGITAL CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2014165873
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an extremely low power consumption and low cost digital control system configured for high speed feedback control.SOLUTION: The digital control system includes: a sensor 102 for detecting a state of a controlled object 101 as an analog voltage V; A/D conversion devices 103, 104 for outputting a result of magnitude comparison of the analog voltage V detected by the sensor 102 with reference voltages ref1, ref2 as a binary digital signal; and a digital signal processing section 107 for outputting a control signal S for approximating the state of the controlled object to a desired value on the basis of the digital signal output from the A/D conversion devices 103, 104. Reference voltages depending on the desired value are input into the A/D conversion devices 103, 104. Comparators are preferably used as the A/D conversion device.
