摘要
This paper investigates the problem of cyber-physical systems in the presence of false data injection attacks. When the communication network connects the controller and the actuator, malicious adversaries can execute false data injection attacks to modify the control commands, deteriorating the performance of the system. A more general attack model is established to describe false data injection attacks including multiplicative and additive attacks. To effectively mitigate such attacks, an output-based secure controller is designed. Sufficient criteria are derived to guarantee that the cyber-physical system under such attacks is stochastically stable. Furthermore, a condition is proposed to design the secure control gain using singular value decomposition, providing a more specific form of the controller. Finally, simulation results are provided to illustrate the effectiveness of the proposed secure control scheme.
