Abstract

The clock synchronization of GPS navigation system is a key technology. This paper is based on GPS clock system, aiming at the asynchronous problem of GPS in the clock, and establishes a more realistic nonlinear dynamic model with coupling delays and delays in the dynamical nodes than before. The clock lag synchronization criteria for the model have been studied. Via the theory of Lyapunov stability, adaptive control technique and delay control methods, we design the adaptive lag feedback synchronization controller. It should be pointed out that the node dynamic need not satisfy the very strong and the coupling matrices are not assumed to be symmetric. The accuracy, real-time, stable and reliable clock data is acquired. Finally, the numerical example of the adaptive lag synchronization problem has been also provided to demonstrate the effectiveness of the theory.
