Control of Independently Rotating Wheels with MR Dampers (2024)
Presentation / Conference Contribution

This paper studies the control of independently rotating wheels (IRWs) in railway vehicles with the use of magnetorheological dampers. The development of a semi-active strategy for steering/guidance control is presented. A conventional bogie vehicle... Read More about Control of Independently Rotating Wheels with MR Dampers.
