Hierarchical hybrid control: an IVHS case study

A case study of the difficulties associated with the design of hybrid control systems is presented. The authors use an intelligent vehicle highway system (IVHS) architecture as their example of a hierarchical hybrid system. The authors point out that, even though conventional analysis tools suggest that the proposed design should fulfill certain performance requirements, the simulation results show that it does not. The authors consider this as an indication that the conventional tools currently in use for the design and verification of control systems may be inadequate for the design of hierarchical control of hybrid systems.>
