Electrospinning technique is currently one of the most important methods for preparing nanofiber. It is important and essential to analyze the distribution of electric field in electrospinning machine. The electric field’s distribution in the typical electrospinning device was calculated and analyzed based on finite element calculation theory of electric field. The electric field is optimized b...

The power electronics inverter can be considered as the weakest link in an electric drive system, hence the focus of this research work is on the detection of fault conditions of the inverter. A machine learning framework is developed to systematically select torque-speed domain operation points, which in turn are fed to an electric drive model to generate signals for training an artificial neu...

On the basis of the shifting process of automated mechanical transmissions (AMTs) for traditional hybrid electric vehicles (HEVs), and by combining the features of electric machines with fast response speed, the dynamic model of the hybrid electric AMT vehicle powertrain is built up, the dynamic characteristics of each phase of shifting process are analyzed, and a control strategy in which torq...
