Software rejuvenation is a cyberdefense mechanism that periodically resets the mission control software of a system to limit the impact of cyberattacks, activating in case it is necessary a safety controller to guarantee that the system returns to a target safe set. Unlike other works that consider feedback gains as mission controllers, here we propose a tree-based model predictive control scheme to explicitly account for the software refresh events and the possibility of cyberattacks. The benefits of the proposed method are illustrated using a simulated microgrid as a case study.
