Due to the high conversion efficiency and good frequency response, Giant Magnetostrictive Actuator (GMA) has been widely used in the machining field. A hysteresis model composed of the phase-lag transfer function and the linearity model is established to meet different working conditions of the GMA. Identifying the parameters in both section, a feed-forward control based on the direct inverse model...
With the ability to induce ultra-high carrier density change (> 1015 cm−2) in the channel in a three-terminal device geometry, electric double layer transistors (EDLTs) using ionic liquid gating are attracting increasing interest in device research to electrostatically induce phase transition and to demonstrate proof-of-principle switches.[1] However, the field-effect measurements are non-trivial...
In order to improve the electrical characteristics of transformer oil-impregnated pressboard, transformer oil-based nanofluids were used to impregnate pressboards. It is found that nanofluid-impregnated pressboard (NP) exhibits substantially higher AC and DC breakdown voltage than that of pure oil-impregnated pressboard (OP). Pulse electroacoustic measurement (PEA) was carried out to study the difference...
