  Accurate local state measurement is important to ensure the reliable
operation of distributed multi-agent systems (MAS). Existing fault-tolerant
control strategies generally assume the sensor faults to be bounded and
uncorrelated. In this paper, we study the ramifications of allowing the sensor
attack injections to be unbounded and correlated. These malicious sensor
attacks may bypass the conventional attack-detection methods and compromise the
cooperative performance and even stability of the distributed networked MAS.
Moreover, the attackers may gain access to the actuation computing channels and
manipulate the control input commands. To this end, we consider the resilient
containment control problem of general linear heterogeneous MAS in the face of
correlated and unbounded sensor attacks, as well as general unbounded actuator
attacks. We propose an attack-resilient control framework to guarantee the
uniform ultimate boundedness of the closed-loop dynamical systems and preserve
the bounded containment performance. Compared with existing literature
addressing bounded faults and/or disturbances that are unintentionally caused
in the sensor and actuator channels, the proposed control protocols are
resilient against unknown unbounded attack signals simultaneously injected into
sensor and actuator channels, and hence are more practical in the real-world
security applications. A numerical example illustrates the efficacy of the
proposed result, by highlighting the resilience improvement over the
conventional cooperative control method.
