摘要：

This paper deals with the encryption-decryption-based passive fault-tolerant consensus control problem for a class of linear multi-agent systems subject to loss-of-effectiveness and additive actuator faults. Both the secure communication and fault tolerance issues are investigated, and their impacts on the consensus are examined. To ensure the communication security, two encryption-decryptionbased fault-tolerant consensus control schemes are proposed, with which the original state of the local agent is first encrypted into a series of codewords and then decrypted by other agents to realize data privacy preserving. The necessary and sufficient condition is established for the addressed consensus problem under the adopted controller structure. A series of numerical examples are given to verify the effectiveness of the developed consensus control strategy. (C) 2021 Elsevier Ltd. All rights reserved.
