Control Design for Cyber-physical Systems Under Attacks
Dr. Márcio J. Lacerda, Ph.D.
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, allowing the integration of computation with physical processes. Security and privacy are key factors that must be taken into consideration in the design, development, and operation of CPS. The existence of malicious agents that intend to degrade the system’s performance through cyber attacks is a reality in this scenario. The denial of service (DoS) attack is one of the most common and easy to implement. It consists of launching a large amount of information in the communication channels to block the ability of the systems to send and receive data, essential for the correct operation of the CPS. This talk will discuss the main security issues in CPS systems, with particular attention to DoS attacks. Linear Matrix Inequalities will be employed to present the design conditions for CPS in the presence of cyber-attacks. At the end of this talk, we will discuss some perspectives for future research on this topic.
