Event-triggered secure observer-based control for cyber-physical systems via candidate selection technique
This paper focuses on designing a class of secure controller with well-designed event-triggering scheme and secure state observer for cyber-physical systems (CPSs) under sparse sensor attacks. Through designing an observer where the basic idea is to reconstruct the correct state through removing the measurements being compromised, an observer-based controller is proposed. Then, a novel candidate selection algorithm is designed to select an appropriate candidate set such that the norm of the residual signal is convergent. By combining the constructed observer-based controller and the candidate selection algorithm, a secure observer-based control algorithm is proposed such that the system state converges to a neighborhood of zero even if some measurements are compromised. Finally, an illustrative example is considered and it is shown that the proposed methods are effective.
