INVESTIGATION OF VEHICLE SUSPENSION CONTROL STRATEGIES WITH WHEEL MOTION MEASUREMENTS: DELAYED RESONATOR AND EXTENDED GROUND HOOK CONTROL
MERT SEVER, AHMET KIRLI
In this study a novel active suspension system concept which is based on delayed resonator phenomenon has been investigated. The ground hook control policy is employed for performance evaluation, since both control policies only use unsprung mass motion measurement. Mathematical modelling of the 6 DOF half vehicle model with bounce and pitch motions and delayed resonator are explained. Random road profile based on ISO2631 standard is used as disturbance. Vibration mitigation and energy consumption levels are specified as performance measures. Finally, numerical simulation studies are carried out. The effect of the disturbance properties such as road grade and travel speed, on the performance has also been analyzed.
