Title: "How control theory can contribute to safety in cyber-physical systems?"
Abstract: With the advance of computation and communication systems, the control design for dynamic systems has become even more challenging. In this context, the class of cyber-physical systems (CPS) has emerged. In a CPS, devices communicate with each other and the physical world through sensors and actuators, integrating computation with physical processes. This integration, however, introduces vulnerabilities due to the threat of malicious agents that intend to degrade the system’s performance through cyber attacks. In this talk, I will explore how control theory can contribute to safety in CPS, focusing on stability certificates, control, and filter design for systems under the threat of denial-of-service (DoS) attacks and transmission failures. Different actions will be presented to mitigate the effects of the attack on the system. Linear Matrix Inequalities will be employed to present the design and analysis conditions. Additionally, I will discuss potential directions for future research in this topic.
