Publication number: 20230195844Abstract: A learning control device according to one embodiment includes one or more hardware processors. The hardware processors function as an update unit, a calculation unit, and a correction unit. The update unit serves to update a modified control input in accordance with a tracking error. The modified control input is used during a learning trial. The calculation unit serves to calculate a lag in a learning control start time in accordance with a state of a control target at a start of the learning control. The learning control start time is a time at which learning control starts. The correction unit serves to correct the modified control input having been updated by the update unit. The modified control input is corrected by using the lag to have a value obtained by offsetting the lag.Type: ApplicationFiled: August 29, 2022Publication date: June 22, 2023Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Makihiko ISHITANI, Shinji TAKAKURA, Yoshiyuki ISHIHARA
