In order to analyze the problem of signal power frequency interference when the single end of the sensor is connected to the ground. The circuit model of the power frequency crosstalk voltage on the core wire is established. The electromagnetic field distribution around the shielding layer is analyzed base on the finite element software ANSYS. And the calculation formula of crosstalk voltage on cable...
The voltage fluctuation between the train body (TB) and the train’s wheel axis (TB voltage fluctuation for short), might cause electromagnetic interference (EMI) on brake control unit (BCU) speed sensor in some high-speed trains (HSTs), which may cause faulty measurement of train speed and incorrect operation of train door. Using a relevant event that occurred in China railways high-speed 380CL-type...
This paper examines a passivity-based I/O approach for stabilization of large scale networked control systems (NCSs) with event-driven communication. We use a cellular model to model the large scale NCSs and assume that each subsystem is an output feedback passive (OFP) system. We propose a distributed event-driven communication strategy, where each subsystem broadcasts its output information to its...
Dual-band and tri-band SIR bandpass filters with compact coupling and sizes reduction are proposed, and two paths coupling is introduced. In the new design, split ring SIR and DGS techniques are applied to not only reduce the size but also improve the filter frequency responses. The presented filters have advantages of compact and novel structures, smaller sizes compared to the traditional SIR bandpass...
