Memoryless H/sup /spl infin// controllers for state delayed systems
TL;DR: The controller is a delay independent stabilizer for the state delayed system, which also reduces the H/sup /spl infin// norm of the closed loop transfer function, from the disturbance to the controlled output, to a prescribed level.
Journal ArticleDOI
Fault diagnosis of a power transformer using an improved frequency-response analysis
TL;DR: In this paper, a synthetic spectral analysis is proposed to deal with wideband frequency responses of each phase, which augments low and medium-frequency components, and equalizes the frequency intervals of a resulting combined curve by a log-frequency interpolation.
Journal ArticleDOI
Inkjet-printed stretchable silver electrode on wave structured elastomeric substrate
TL;DR: In this paper, high performance and stable inkjet-printable stretchable silver electrodes on wave-structured elastomeric substrates were reported, showing good mechanical stability during 1000-time fast (1 mm/s) cycling test with 10% tensile strain.
Journal ArticleDOI
Wearable Device-Based System to Monitor a Driver’s Stress, Fatigue, and Drowsiness
TL;DR: Using the proposed system, the abnormal conditions of the driver can be detected and distinguished, and this advantage contributes to safer and more comfortable driving.
Proceedings ArticleDOI

TL;DR: In this paper, the authors proposed a novel instantaneous current sharing control scheme ensuring a fast dynamic response and an equal load sharing capability in a parallel connected UPS (inverter) which is based on the instantaneous output voltage control with the current deviation control and the instantaneous current deviation cancellation control utilizing the current share bus circuit.
