The objective of this thesis is to develop innovative control strategies for electromechanical active suspensions of Connected and Autonomous Electric Vehicles (CAEVs). These strategies are based on Fractional-Order Systems in order to generalize and optimize the classical Sky-Hook and Ground-Hook control laws. In this context, the suspension becomes a controlled subsystem contributing to comfort, road holding, safety, and vehicle dynamic performance.
The adopted approach is based on a decomposition of the vehicle operation into three Operational Design Domains, denoted ODDs.
ODD1 is oriented toward vibration comfort through Sky-Hook strategies: SHO, CSHN, CSHG, and CSH1G.
ODD3, associated with emergency situations, is oriented toward road holding and active safety through Ground-Hook strategies: GHO, CGHN, and CGHG.
Between these two domains, ODD2 constitutes a transition zone in which a mixed strategy is proposed.
The main contribution of this thesis lies in the design of a supervised multi-controller control architecture. This architecture makes it possible to identify the operational driving domain in real time and to dynamically adapt the corresponding control strategy.
