Abstract
A dead time estimation device capable of accurately estimating a dead time in a control system is provided. A dead time estimation deviceincludes a dead time calculation sectionconfigured to obtain a dead time L{circumflex over ( )}'1 with which an evaluation function J in Equation (1) is at minimum[Equation 7]  (1)where G{circumflex over ( )}/eis a frequency characteristic of an element from which a dead time element is removed from a transfer function of a control target P and G{circumflex over ( )}′ is a transfer function not including the dead time element in the control target P.
