Patent number: 11514910Abstract: A server is an interactive system that performs the interaction by performing a reverse question with respect to an input by the user and providing response content. An input acquisition unit and an answer generation unit constitute an interaction execution unit that repeatedly performs the interaction until a question sentence and an answer, which are the response content, satisfy a prescribed condition. Further, the stoppage determination execution unit performs control for stopping the interaction performed by the input acquisition unit and the answer generation unit based on the interaction state by the user or the other user. In a case where the interaction is stopped, the output unit provides the question sentence and the answer thereof at the time of stoppage to the communication terminal.Type: GrantFiled: December 27, 2018Date of Patent: November 29, 2022Assignee: NTT DOCOMO, INC.Inventors: Takanori Hashimoto, Hiroshi Fujimoto, Yuriko Ozaki

Patent number: 11366435Abstract: A control device to perform feedback control based on a current value, and output a first voltage value includes a feedforward controller using an inverse model of a plant; a feedforward voltage corrector to correct a voltage disturbance due to a modeling error between the plant and a model of the plant; a repetitive controller to learn periodic current disturbances; and a switch. The switch is ON when the current response is in a steady state, and the repetitive controller learns the disturbances and corrects a command current value. A feedback controller outputs the first voltage value by performing the feedback control based on a current value from the corrected command current value, and inputs the command current value to the inverse model to generate a second voltage value. The control device outputs a sum of the first and the second voltage value as a command voltage value.Type: GrantFiled: April 4, 2018Date of Patent: June 21, 2022Assignees: NIDEC CORPORATION, THE UNIVERSITY OF TOKYOInventors: Hiroshi Fujimoto, Linfeng Lan, Tomonari Mori, Masanori Watahiki
