Description
Summary:In this paper, the actuator fault estimation problem is investigated for a multi-agent systems. Fault estimation plays a vital role in the field of fault tolerant control or fault accommodation. Firstly, the multi-agent system model with unknown additive actuator faults based on leader-follower structure is given. To get the estimated value of unknown fault, an unknown input observer is designed in this study, by selecting the appropriate gain parameter matrices, the desired fault estimation aim could be achieved. And then the stability of fault estimation observer error systems is guaranteed according to Lyapunov approach. Finally, simulation example is used to verify the effectiveness of the proposed technique.
