title = "Separated periodic/aperiodic state feedback control using periodic/aperiodic separation filter based on lifting",
abstract = "Automatic machines have recently advanced into diverse environments. A periodic state and an aperiodic state of the system usually have different physical meanings and require different control objectives in the diverse environments. To enable a new control approach based on the periodic and aperiodic states for the different control objectives, a periodic/aperiodic separation filter (PASF) that separates a state into a periodic state and an aperiodic state is proposed in this paper. Furthermore, using the PASF, the periodic/aperiodic state feedback control and the separation principle are established.",

note = "Funding Information: This paper proposed the PASF that separates a signal into a periodic signal and an aperiodic signal. Furthermore, the periodic/aperiodic state feedback control and the separation principle were established. The PASF achieved accurate periodic state estimation, proper separation, and periodic/aperiodic state feedback control. Hisayoshi Muramatsu received the B.E. degree in system design engineering and the M.E. degree in integrated design engineering from Keio University, Yokohama, Japan, in 2016 and 2017, respectively. He is currently a Ph.D. Student at Keio University, Yokohama, Japan. His research interests include control theory, motion control, and mechatronics. Seiichiro Katsura received the B.E. degree in system design engineering and the M.E. and Ph.D. degrees in integrated design engineering from Keio University, Yokohama, Japan, in 2001, 2002, and 2004, respectively. From 2003 to 2005, he was a Research Fellow with the Japan Society for the Promotion of Science (JSPS). From 2005 to 2008, he was with the Nagaoka University of Technology, Nagaoka, Japan. Since 2008, he has been with Keio University. In 2017, he was a Visiting Researcher with the Laboratory for Machine Tools and Production Engineering, RWTH Aachen University, Aachen, Germany. His research interests include applied abstraction, human support, data robotics, wave system, systems energy conversion, and electromechanical integration systems. Prof. Katsura serves as an Associate Editor for the IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS.
