Abstract

The adaptive adjustment mechanism is applied to the stabilization of an internally coupled map lattice system defined by xi,t+1=G((1αiβi)xi,t+αixi+1,t+βixi1,t), where f: is a nonlinear map, and α and β are nonnegative coupling constants that satisfy the constraint αi+βi<1, for all x, i=1,2,,n. Sufficient conditions and ranges of adjustment parameters that guarantee the local stability of a generic steady state have been provided. Numerical simulations have demonstrated the effectiveness and efficiency for this mechanism to stabilize the system to a generic unstable steady state or a periodic orbit.
