摘要

The global synchronization of chaotic Lorenz-Stenflo systems via variable substitution control is studied. First, a master-slave synchronization scheme with variable substitution control is constructed. Based on this scheme, some sufficient criteria for the global chaos synchronization of master and slave Lorenz-Stenflo systems via various single-variable coupling are derived and formulated in the form of algebra. Numerical examples are provided to verify the effectiveness of the criteria.
