COMPENSATION CIRCUIT AND METHOF OF SAMPLING DELAY IN A DIGITAL CONTROL SYSTEM

摘要

The compensation circuit comprises an error detector (1) detecting the position deviation error; a velocity flow file generator (2) making the velocity flow file based on the position deviation error; a delay means (3) delaying the position data to one sample period; a velocity calculating means (4) calculating current velocity based on the output of the dlay means (3) and the current position; a velocity delay compensation means (5) compensating the velocity value to the sampling time; a velocity deviation calculating means (6) calculating the velocity deviation based on the compensation velocity and the target velocity of the velocity flow file generator (2); a deviation compensation means (7) compensating the control object (8) based on the velocity deviation calculating means (6).
