LQ-Servo Design for Automatic Train Control of Urban Rail Vehicle

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Design of Integrated Monitoring and Early Warning System of Urban Rail Transit Train Running State

The monitoring and warning of urban rail transit is the core of operation management, and the breadth and depth of the monitoring range directly affect the quality of urban rail transit operation. For the current domestic monitoring system, most of the critical equipments and technologies are introduced from abroad; it is diseconomy, and also causes hidden danger. Realizing the localization of ...

Multiobjective robust design optimization of rail vehicle

This work deals with the multiobjective robust design optimization of rail vehicle systems moving in short radius curved tracks. Two criteria are considered simultaneously, i.e., safety and comfort. We showed that the deterministic optimal solutions, for the nominal design parameters, can be altered seriously by the design parameters uncertainty. A new algorithm that combines Genetic Algorithms...

‌Optimal design of onboard energy storage systems with volume limitation for urban electrical rail transportation

Train braking energy regeneration in urban electrical rail transportation systems can reduce energy consumption and operational cost of the system. In this paper, optimal design of an onboard energy storage system (OESS) with volume constraint is presented for urban electrical rail transportation systems (ERTS). Onboard super-capacitors are considered as the storage system. The objective functi...
