Abstract Paper reports the main results of a systematic study on longitudinal train dynamics (LTD) long freight trains, equipped with radio communication. The simulation have been used to prepare an experimental test campaign Distributed Power System (DPS) technology. simulations refer up/down and level track they compare LTD trains without DPS, for different operations link conditions. DPS tec...

Finite element or finite volume discretizations of distributed parameter systems (DPS) typically lead to high order finite dimensional systems. Model approximation is then an important first step towards the construction of optimal controllers. However, model reduction methods hardly take model uncertainties and parameter variations into account. As such, reduced order models are not well equip...

Based on the idea of fault detection and isolation (FDI) for the distributed parameters system, a practical approach of sub-sea pipelines leak detection and location is discussed. The discrete fluid transient equation is linearized and coupled with the extended Kalman filter (EKF) to estimate system state where the only observed data were inlet and outlet flow rate and pressure. The leak estima...

In this work, the boundary control of a distributed parameter system (DPS) modeled by parabolic partial differential equations with spatially varying coefficients is studied. An infinite dimensional state space setting is formulated and an exact transformation of the boundary actuation is realized to obtain an evolutionary model. The evolutionary model is used for subsequent linear quadratic re...

This paper discusses the design of BATRUN Distributed Processing System (DPS). We have developed this system to automate the execution of jobs in a cluster of workstations where machines belong to different owners. The objective is to use a general purpose cluster as one massive computer for processing large applications. In contrast to a dedicated cluster, the scheduling in BATRUN DPS must ens...
