Control Acquisition Attack of Feedback Control System by False Data Injection
Abstract
This work investigates and develops a novel method of cyberattack which aims to take control of an autonomous aerospace system by injection of false measurement data. This work demonstrates that an attacker can use proportional-integral control acting on the error between the attacker’s input and the system output in order to take over control of a feedback control system. It is shown that this approach is system agnostic and can be used to takeover a system without any knowledge of the model or controller operating on the system. This work also explores the effects of the attacker on the observability, controllability, and stability of the system under attack. The attack is demonstrated in both simulation and hardware experiments. These experiments serve to demonstrate the strengths and weaknesses of the attack under different control scenarios. The experimental results show that there is a trade-off for the attacker between exerting effective control and eliminating the control of the victim. Gain scheduling can be used to overcome this by choosing the appropriate gains for the action being performed, but effective control and victim-rejection will always conflict with one another.
