Simulation and formal modelling of yaw control in a drive-by-wire application

Cyberphysical systems, with their interdependence between physical behaviour and digital control, need insights from frequency domain control engineering, state space control engineering and discrete formal systems theory for their proper description. Neglecting any of these, results in descriptions that omit essential details. Hybrid Event-B is a formalism that enables all the relevant detail to be assimilated. A case study based on yaw control for the KURT e-vehicle is used as a testbed to explore the effective interaction between the various needed disciplines in exploring a specific design issue, the formalisation of yaw control discretization, using Hybrid Event-B.
