This paper addresses the adaptive asymptotic synchronization problem of a class of leader-follower large scale networked systems against communicated signal attenuation and actuator bias faults. Adaptive mechanisms are constructed to estimate each unknown faulty factor of communications and actuators on-line. Based on the estimations, an adaptive compensation controller is designed to automatically remove the unexpected impacts of communication and actuator faults. Through the adaptive adjustment parameters and Lyapunov functions, the achievement of asymptotic synchronization of the leader-follower large-scale networked system with the improper actuator and faulty transmitted signals is obtained. Finally, the synchronization results are validated by a multiple vehicle large-scale device.
