Abstract
A method and system to control a cyber physical system using an observer-based controller including a detector to determine an occurrence of an attack on the cyberphysical system and to inform the observer-based controller via a signal. The observer estimates a system state of the cyberphysical system based on at least partial information about the cyber physical system. The observer-based controller is configured with a predetermined observer gain and controller gain. The observer-based controller is configured to control the cyberphysical system using an estimated error determination that is altered depending on a type of cyber attack. The observer-based controller is configured to control the cyberphysical system subjected to cyber attacks in both a forward channel connecting at least one sensor with the observer and a backward channel connecting the observer-based controller with actuators.
