FEEDBACK CONTROL DEVICE, RANDOM DITHER BINARIZATION DETECTOR, AND FEEDBACK CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a feedback control device capable of high-precision output control even when using a simple sensor.;SOLUTION: A feedback control device of the present invention includes: a random signal generation unit 40 for generating a random signal w attached to an output y representing a physical quantity of a control object 20; a binary quantization sensor 30 for detecting a sum signal in which the random signal w is added to the output y and outputting a discrete feedback control variable corresponding to the sum signal; a control unit 10 for controlling a control input u to the control object 20 so that a control error becomes 0 that is a difference between a target value r representing a desired physical quantity of the control object 20 and a feedback control variable v being a quantized value of the sum signal by the binary quantization sensor 30.;COPYRIGHT: (C)2015,JPO&INPIT
