In this article, a fault‐tolerant control (FTC) scheme for linear multiagent systems (MASs) subject to time‐varying loss of effectiveness and time‐varying additive actuator faults as well as external disturbance is investigated. The main objective of the proposed FTC approach is to keep the performance of an MAS after the occurrence of actuator faults similar to the healthy one. The envisaged adaptive virtual actuator for each agent does not require a separate fault detection, isolation, and identification unit nor does it require any information regarding the mission of the MAS. It is shown that the difference between the states of each agent before and after the occurrence of actuator faults can be made arbitrary small and the ultimate bounds of the state error are also obtained. Furthermore, it is shown that for constant actuator faults the state error of each agent converges to zero. Simulation results corresponding to a team of F‐8 aircraft and a heterogeneous MAS with the different order demonstrate and illustrate the effectiveness of our proposed FTC scheme.

基于自适应虚拟执行器的异构线性多主体系统独立于任务的容错控制

在本文中，研究了线性多主体系统（MAS）的容错控制（FTC）方案，该方案受有效性的时变损失和时变附加执行器故障以及外部干扰的影响。提出的FTC方法的主要目标是在执行器故障发生后（与正常故障类似）保持MAS的性能。为每个代理程序设想的自适应虚拟执行器不需要单独的故障检测，隔离和识别单元，也不需要有关MAS任务的任何信息。结果表明，致动器故障发生之前和之后每个代理的状态之间的差异可以任意减小，并且还可以得到状态误差的最终界限。此外，结果表明，对于恒定的执行器故障，每个代理的状态误差收敛到零。对应于F-8飞机和不同顺序的异构MAS团队的仿真结果证明并说明了我们提出的FTC方案的有效性。
