E. Foo et Rm. Goodall, Active suspension control of flexible-bodied railway vehicles using electro-hydraulic and electro-magnetic actuators, CON ENG PR, 8(5), 2000, pp. 507-518
Lighter railway vehicles are going to become the norm in the future as the
operator pushes towards a more economical operation. This paper looks into
ways of applying classical control methods using "skyhook damping" to minim
ise the flexibility effects that arise as a consequence of having lighter v
ehicles, and in particular includes the effects of real actuator dynamics.
Two and three actuators schemes are considered: two of them are located at
the front and rear secondary suspension pivot points, with a third actuator
at the centre of the vehicle primarily targeted at reducing the effects of
the main bending mode of the vehicle body. Hydraulic actuators are used at
the front and rear while an electro-magnetic actuator is connected to the
centre of the vehicle. (C) 2000 Elsevier Science Ltd. All rights reserved.
