In this study, we investigated the effects of exposure to an extremely low frequency magnetic field (ELFMF) on hormone secretion from an islet derived insulinoma cell line, RIN-m. We stimulated RIN-m cells to secrete insulin under exposure to an ELFMF, using our established system for the exposure of cultured cells to an ELFMF at 5 mT and 60 Hz, or under(More)
This paper considers the rotor speed and flux estimation for induction motors, which is one of the key problems in speed-sensorless motor drives. Existing approaches, e.g. adaptive, Kalman filter-based, and sliding mode observer, have limitations such as unnecessarily assuming the rotor speed as a constant parameter, failure to ensure convergence of(More)
Bandwidth limitation hinders the economical and broad application of induction motors promised by speed sensorless drive. This paper proposes an integrated control and observer design for speed sensorless control of induction motors with stator voltage and current measurements. With a general observer structure, the backstepping-based robust control design(More)
