Abstract

The development of formal methods for control design is an important challenge with potential applications in a wide range of safety-critical cyber-physical systems. Focusing on switched dynamical systems, we propose a new abstraction, based on time-varying regions of invariance (control funnels), that models behaviors of systems as timed automata. The main advantage of this method is that it allows for the automated verification and reactive controller synthesis without discretizing the evolution of the state of the system. Efficient and analytic constructions are possible in the case of linear dynamics whereas bounding funnels with conjectured properties based on numerical simulations can be used for general nonlinear dynamics. We demonstrate the potential of our approach with three examples.

Notes

  1. In this paper, we mostly consider state spaces that describe the position and velocity of systems controlled in acceleration. The continuity of trajectories in the state space ensures that the position is always a continuously differentiable function of time.

  2. One should always choose the reference trajectory such that there exists a margin between the reference values and the limit imposed by (8) since otherwise the convergence is very slow.
