摘要：AbstractTime delayspose an important challenge in networked control systems, which are now ubiquitous. Focusing on switched systems, we introduce a framework that provides an upper bound for errors caused by switching delays. Our framework is based onapproximate bisimulation, a notion that has been previously utilized mainly for symbolic (discrete) abstraction of state spaces. Notable in our framework is that, in deriving an approximate bisimulation and thus an error bound, we use a simple incremental stability assumption (namelyδ-GUAS) that does not itself refer to time delays. That this is the same assumption used for state-space discretization enables atwo-step workflowfor control synthesis for switched systems, in which a single Lyapunov-type stability certificate serves for two different purposes of state discretization and coping with time delays. We demonstrate the proposed framework with a boost DC-DC converter, a common example of switched systems.
