Abstract : This paper studies the secure consensus control problem of multi-agent systems under DoS attacks on the sensor, the actuator, and the communication topology. A resilient intermediate estimator based attack tolerant control strategy is proposed. By fully exploiting the hardware redundancies, both of the estimators and the control protocols can be reconstructed online according to different DoS attack scenarios. Finally, the experiment results of the networked multi-axis motion control system are given to verify the effectiveness of the proposed method.

Keyword : DoS attack, multi-agent systems (MASs), networked multi-axis motion control system, resilient intermediate estimator, secure consensus control (SCC).
