[en] In the present paper, a model-based fault/attack tolerant scheme is proposed to cope with cyber-threats on Cyber Physicals Systems. A common scheme based on observers is designed and a state feedback control based on an aperiodic event-triggered framework is given with control synthesis and condition on the switching time.
Classical fault tolerant control with Bilinear Matrix Inequality (BMI) approaches are used to achieve novel and better security strategy based on an event-triggered control implementation.
The purpose in using the event-based implementation would be to reduce (limit) the total number of transmissions to only instances when the networked control system (NCS) needs attention. An illustrative example of the proposed approach applied to a three-tank system is presented.
