Resilient and robust distributed control protocols for multiagent systems under attacks on sensors and actuators are designed. A distributed H control protocol is designed to attenuate the disturbance or attack effects. However, the H controller is too conservative in the presence of attacks. Therefore, it is augmented with a distributed adaptive compensator to mitigate the adverse effects of attacks. The proposed controller can make the synchronization error arbitrarily small in the presence of faulty attacks, and satisfy global L -gain performance in the presence of malicious attacks or disturbances. A significant advantage of the proposed method is that it requires no restriction on the number of agents or agents' neighbors under attacks on sensors and/or actuators, and it recovers even compromised agents under attacks on actuators. Simulation examples verify the effectiveness of the proposed method.
设计了针对多智能体系统在传感器和执行器受到攻击情况下的弹性且鲁棒的分布式控制协议。设计了一种分布式H控制协议以减弱干扰或攻击影响。然而，H控制器在存在攻击时过于保守。因此，用一个分布式自适应补偿器对其进行增强，以减轻攻击的不利影响。所提出的控制器在存在故障攻击时可使同步误差任意小，并在存在恶意攻击或干扰时满足全局L增益性能。所提方法的一个显著优点是，在传感器和/或执行器受到攻击时，它对智能体数量或智能体邻居数量没有限制，并且在执行器受到攻击时甚至能恢复受损的智能体。仿真示例验证了所提方法的有效性。
