| 英文摘要 |
| In this paper, the adaptive neural network fault-tolerant control strategy is proposed for a class of nonstrictfeedback
stochastic multi-agent systems with output constraints and actuator faults under a directed communication topology.
Neural networks are utilized to approximate unknown nonlinear functions. Furthermore, the barrier Lyapunov function
is employed to deal with the problem of output constraints. Combining backstepping method, dynamic surface control technique
and Nussbaum function, an adaptive neural network fault-tolerant control method is proposed. Based on Lyapunov
stability theory, it is proved that all followers’ outputs can be consistent with the leader’s output. All signals in the closedloop
systems are semiglobally uniform ultimate bounded in probability and the output of systems can be limited within the
given compact set. Finally, the effectiveness of the proposed control scheme is verified through numerical simulation. |
