Abstract(E)	This paper carries out a comprehensive study of different actuation schemes and control approaches for active steering of railway vehicles. The study concentrates on active steering techniques for rail vehicles with axled wheelsets including the solid-axle wheelsets and independently-rotating wheelsets, but wheel-pairs without axles are also briefly mentioned. Various actuation configurations are discussed, and advantages and drawbacks of those schemes are investigated. A number of control methods including modern controllers and classical intuitively-formulated controllers are studied, and their performances are assessed. Potential benefits of the use of a combination of modem control technology and mechatronic approach are demonstrated, and in particular solutions for the difficult design trade-off between the stability and the curving performance are presented. Overall the paper provides an authoritative assessment of actively-steered wheelsets, including practicalities such as actuation and sensing requirements.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.
