This paper presents a control law for a low frequency active suspension system necessary for the implementation of the strategy defined in the first paper. The structure of the proposed control law is based on cooperation between feedforward and feedback. Feedforward design is based on the vehicle physics. The feedback law is synthesized from CRONE control-design method, french acronym of “Commande Robuste d’Ordre Non Entier” (non integer order robust control). Modeling, robust control-design in frequency-domain, optimal approach, stability analysis and performance are presented in this paper.
