Cooperative control of high-speed trains can improve the safety and efficiency railway transportation. However, velocity distance overshoots in cooperative multiple is an undesirable behavior, which will lead to unsafe inefficient train operation. To address this issue, a predictive set point modulation approach for proposed. First, cyber-physical modeling presented. The longitudinal dynamic ch...

Access to online experiments permitted by the current technology offers more flexibility than local presence. However, it also presents new challenges, such as which information should be transfered from the process to the remote user to describe with sufficient details the progress of the experimentation, and from the user to the process to control it and to test interesting working conditions...

Databases have been proposed as the chosen platform to develop automated control systems for environments where the state of the system changes rapidly, and actions need to be taken with timing constraints, such as stock trading, air tra c control, network management and process control to name a few. The workload in such systems consist primarily of two types: (a) updates, which report the sta...

The paper analyzes some of Tesla's works and his most remarkable views concerning the problem of formulating theoretical bases of automatic control. As a tribute to Tesla's work on remote control of automated systems, as well to his (at the time) far-seeing visions, special attention is paid to solving complex problem of control and feedback application. A more detailed discussion of the way an...

In this paper the effect on energy consumption and pollution of fuzzy automatic control of a rotary kiln is investigated. The computer-based fuzzy control system is installed at the Larko ferronickel plant in Larymna, Greece, by the Danish firm F .L. Smidth & Co. A/S. Operation characteristics for the manual operation against automatic control are defined and compared. Preliminary results show ...

The language of rail rapid transit and train control technology contains many specialized terms that may be unfamiliar to the general reader. This glossary has been prepared as an aid to understanding the terminology used in the report. It is also contemplated that the glossary may be useful as a reference for additional reading on the subject of ATC and transit system engineering. For this rea...

Echolocating animals adjust the transmit intensity and receive sensitivity of their sonar in order to regulate the sensation level of their echoes; this process is often termed automatic gain control. Gain control is considered not to be under the animal's cognitive control, but previous investigations studied animals ensonifying targets or hydrophone arrays at predictable distances. To test wh...

high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

The modeling methodology of tilting train is studied. The vehicle and pantograph are considered as nonlinear multiple rigid body systems, and the catenary is modeled by FEM method. The electrical mechanical actuators for carbody and pantograph tilting control are also considered in the tilting train model. The method of on-line curving detection, filtering and control is adopted for the tilting...

Gain and time-constant factors shift the inverse process relative to its feedback controller. A new robustness plot cross-graphs these shift factors that take the loop to the stability boundary as a function of frequency.
