Energy-Efficient Train Driving Based on Optimal Control Theory

Energy efficiency on train control: design of metro ATO driving and impact of energy accumulation devices

Reduction in energy consumption has become a global concern, and the EU is committed to reducing its overall emissions to at least 20% below 1990 levels by 2020. In the transport sector measures are focused on planning, infrastructure, modal change, the renewal of vehicles and also programmes for efficient driving. In metro lines equipped with ATO systems, the ATO speed profiles are designed to...

Controlling Train Power Consumption with Energy Storage Based on Fuzzy Control - Case Study on Line 3 of Tehran Metro

New high-speed trains need modern energy management methods to reduce energy consumption. A fuzzy method based control method was used to solve this problem in this paper and evaluated the results on basis of data in Tehran metro line 3. Recovering the maximum amount of train kinetic energy when it is in the braking mode and optimal division of traction systems demand between energy storage sys...

Review of energy-efficient train control and timetabling

The energy consumption of trains is highly efficient due to the low friction between steel wheels and rails, although the efficiency is also influenced largely by the driving strategy applied and the scheduled running times in the timetable. Optimal energy-efficient driving strategies can reduce operating costs significantly and contribute to a further increase of the sustainability of railway ...

Optimal Driving Strategies for a Train Journey with Speed Limits

How should a vehicle he driven to minimise fuel consumption? In this paper we consider the case where a train is to be driven along a straight, level track, but where speed limits may apply over parts of the track. The journey is to be completed within a specified time using as little fuel as possible. For a journey without speed limits, the optimal driving strategy typically requires full powe...
