An efficient model for twisted-pair cables with discontinuities and stubs for discrete time simulations
نویسندگان
چکیده
This paper describes an efficient model for twistedpair cables suitable for discrete time simulations. The model uses a pole-zero approximation for the cable losses, and a modified s-parameter approach to model the reflections due to discontinuities and stubs. Use of this model can improve simulation times by a factor of ten compared to using the conventional method of including the channel impulse response in a discrete time simulator. Simulation results for a twisted-pair cable network, including a stub, are compared with actual cable measurements.

High-frequency characterization of twisted-pair cables
A wave propagation method model is proposed for the extraction of propagation parameters of high-bit rate digital subscriber twisted-pair cables. The model is derived from the scattering parameters of a transmission line. The frequency dependence and the skin effect are studied. Experimental simulations are performed to evaluate the accuracy of the extracted parameters. Good agreement is found ...
متن کاملA new conforming mesh generator for three-dimensional discrete fracture networks
Nowadays, numerical modelings play a key role in analyzing hydraulic problems in fractured rock media. The discrete fracture network model is one of the most used numerical models to simulate the geometrical structure of a rock-mass. In such media, discontinuities are considered as discrete paths for fluid flow through the rock-mass while its matrix is assumed impermeable. There are two main pa...

In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...
