Title:
CONTROL DEVICE FOR ASTATIC SYSTEM HAVING DEAD TIME
Document Type and Number:
WIPO Patent Application WO/2014/061682
Kind Code:
A1
Abstract:
A control device (1) for controlling a control target comprising an astatic system (2) that has dead time is provided with: a dead time compensation system (5) that compensates for dead time at the control target based on the dynamic characteristics of the control target; and an integration error compensation system (6) that compensates for integration errors originating in the dead time compensation system (5). The integration error compensation system (6) comprises: an ideal response unit (7) in which the dynamic characteristics of the control target while in a state in which interference is not input are used as a model; and a correction unit (8) that is configured to correct a comparative value for the output of the ideal response unit (7) and the output of the control target and subsequently input the result to the control target.
