Sound Control Synthesis with Logic and Data

Abstract

We are witnessing an inter-disciplinary convergence between scientific areas underpinned by model-based reasoning and by data-driven learning. Access to information-rich data has to be traded off with a demand for safety criticality: cyber-physical systems are exemplar applications. In this talk, I shall report on ongoing research in this cross-disciplinary domain at OXCAV, the Oxford Control and Verification group. 

In particular, I shall present recent work on CEGIS, a ``counterexample-guided inductive synthesis'' framework for sound synthesis tasks that are relevant for dynamical models, control problems, and software programs. I shall elucidate the ins&outs of the CEGIS framework, and display its workings on a few problems: synthesis of certificates for dynamical and control models; hybridisation of nonlinear dynamics for safety verification; and an application in real-time autonomy.
