Unexpected yaw disturbances, such as braking on unilaterally icy roads, side wind forces and tire ruptures,are very dicult to handle by the driver of a road vehicle, due to his/her large panic reacti...
Active Control of Seat Vibrations of a Vehicle Model Using Various Suspension Alternatives
PID control Vehicle model Active suspensions
2009/10/12
The dynamic behavior of a non-linear 8 degrees of freedom vehicle model having active suspensions and a PID controlled passenger seat is examined. The non-linearity occurs due to dry friction on the d...
