Rotor time constant identification is necessary for high-performance indirect field oriented control of induction motor drives. Meanwhile, speed sensorless technique has many advantages such as low ...

The performance of mass spectrometers with limited pumping capacity is shown to be improved through use of a discontinuous atmospheric pressure interface (DAPI). A proof-of-concept DAPI interface was ...

Considering the variations of inertia in real applications, an adaptive control scheme for the permanent-magnet synchronous motor speed-regulation system is proposed in this paper. First, a composite ...

What Is the Best VFD Design and Installation Plan? Variable frequency drives (VFDs) are widely used in industrial fan, pump ...

Loading speed and temperature have certain influence on interface properties, which affect their application in the service environment. In this paper, the interface intrinsic strength of ...

Supercomputer simulations show how to speed up chemical reaction rates at air-water interface by Coury Turczyn, Oak Ridge National Laboratory edited by Lisa Lock, reviewed by Robert Egan Editors ...
