چکیده :

This paper presents an active robust fault-tolerant consensus control of nonlinear Multi-Agent Systems (MASs) with external disturbances. It is assumed that the states are not available for measurement. Moreover, the follower agents might be simultaneously subjected to multiplicative actuator faults. Therefore, an integrated design and analysis of observer-based fault estimation and fault-tolerant cooperative control schemes will be proposed. Here, a fuzzy wavelet neural networks is introduced in order to approximate the unknown time-varying multiplicative fault function. Further, a robust H_∞ fault-tolerant cooperative control scheme using linear matrix inequalities will be developed. To demonstrate the effectiveness of the proposed decentralized fault-tolerant control approach, simulation results on a group of rotary-wing air vehicles are provided.
