Predictive Function Control for Communication-Based Train Control (CBTC) Systems

Predictive Function Control for Communication - Based Train Control ( CBTC ) Systems Regular Paper

In Communication‐Based Train Control (CBTC) systems, random transmission delays and packet drops are inevitable in the wireless networks, which could result in unnecessary traction, brakes or even emergency brakes of trains, losses of line capacity and passenger dissatisfaction. This paper applies predictive function control technology with a mixed  H H / 2 contr...

CBTC (Communication Based Train Control): system and development

CBTC (Communication Based Train Control) systems are known as comprehensive, integrated and intelligent control systems for rail systems including mainline railways, light rails and underground lines in cities. With the development of modern data communication, computer and control techniques, CBTC represents the future direction of rail control systems. At present, CBTC has been used in light ...

A cognitive control approach to interference mitigation in communications-based train control (CBTC) co-existing with passenger information systems (PISs)

As a key component of urban rail transit systems, communications-based train control (CBTC) is an automated train control system using train-ground communications to ensure efficient operation of rail vehicles. In addition to CBTC systems, passenger information systems (PISs) are adopted in urban rail transit systems to improve quality of service (QoS) offered to customers. The interference bet...

Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
