Cover Story: Cyber-physical systems (CPS) need to satisfy complex, time-sensitive objectives (e.g., a drone should persistently surveil a region at fixed time intervals). However, a CPS can be affected by adversaries that can launch timing or actuator attacks. We introduce a new class of durational stochastic games (DSGs) to model CPS–adversary interactions. The satisfaction of objectives under timing and actuator attacks is related to reaching equilibria of the DSG. We develop notions of robustness to quantify the maximal spatial and temporal perturbations of CPS trajectories by an adversary while ensuring the satisfaction of an objective. This research establishes new connections between game theory and security by designing provably correct algorithms to synthesize robust controllers. View this paper

A Differential Game for Optimal Water Price Management

  • Andrea Caravaggio,
  • Luigi De Cesare and
  • Andrea Di Liddo

5 April 2023

This article studies a leader–follower differential game with a finite horizon, where a single buyer reacts to the selling price set by an agency (water supplier). The Open-Loop Stackelberg equilibrium is calculated, assuming that the user dema...
