Active suspension system based on Lyapunov method and ground-hook reference model

An alternative design technique for active suspension system of a vehicle using a developed ground-hook damping system as a reference is proposed. The controller parameters are determined using Lyapunov method and can be tuned to precisely achieve the type of desired response specified by the reference model. The simulation result show that the designed active suspension system based on ground-hook reference model is able to significantly improve the ride comfort and the road holding when compared to a semi-active suspension.
