In recent years, formal methods have been extensively used in the design of autonomous
systems. By employing mathematically rigorous techniques, formal methods can provide …

Hybrid systems describe the interaction of software, described by finite models such as finite-
state machines, with the physical world, described by infinite models such as differential …

There is a growing interest in Industry and Academia in large scale composite systems
where a number of physical processes are interfaced with intelligent units that control them …

Finite-state models of control systems were proposed by several researchers as a
convenient mechanism to synthesize controllers enforcing complex specifications. Most …

Symbolic models are abstract descriptions of continuous systems in which symbols
represent aggregates of continuous states. In the last few years there has been a growing …

In this note, we propose symbolic models for networks of discrete-time nonlinear control
systems. If each subsystem composing the network admits an incremental input-to-state …

This paper introduces a methodology for the symbolic control of nonlinear systems based on
an approximate notion of simulation relation. This notion generalizes existing exact notions …

We present an approach to prove safety (collision freedom) of multi-lane motorway traffic
with lane-change manoeuvres. This is ultimately a hybrid verification problem due to the …

In this paper we present and analyze a novel algorithm to synthesize controllers enforcing
linear temporal logic specifications on discrete-time linear systems. The central step within …

In a series of contributions Olderog et al. have formulated and verified safety controllers for a
number of lane-maneuvers on multi-lane roads. Their work is characterized by great clarity …
