In this paper, we present a generalized lag synchronization-based method to identify the exact topology of uncertain complex networks with time delay and noise perturbation. By designing new controllers and novel adaptive identification rules, the unknown topological structure of the network is successfully identified in the process of synchronization. Meanwhile, we discuss the effect of time delay...
In this paper, cluster synchronization on multiple nonlinearly coupled dynamical subnetworks of complex networks with nonidentical nodes and stochastic perturbations is studied. Based on the general leader–follower’s model, an improved network structure model that consists of multiple pairs of matching subnetworks, each of which includes a leaders’ subnetwork and a followers’ subnetwork, is proposed...
This paper presents a temperature and supply voltage variation-tolerant CMOS relaxation oscillator which is suitable for ultra-low power systems. A low-power low-cost half-period pre-charge compensation scheme is proposed to eliminate influences of the delay of the comparator and the RS latch on the frequency stability of the relaxation oscillator. In a clock period consisting of four working stages...
