ABSTRACT
We provide a scheme for the synchronization of two chaotic mobile robots when a mismatch between the
parameter values of the systems to be synchronized is present. We have shown how meta-heuristic
optimization can be used to adapt the parameters in two coupled systems such that the two systems are
synchronized, although their behavior is chaotic and they have started with different initial conditions and
parameter settings. The controlled system synchronizes its dynamics with the control signal in the periodic
as well as chaotic regimes. The method can be seen also as another way of controlling the chaotic
behavior of a coupled system. In the case of coupled chaotic systems, under the interaction between them,
their chaotic dynamics can be cooperatively self-organized. A synergistic approach to meta-heuristic
optimization search algorithm is developed. To avoid being trapped into local optimum and to enrich the
searching behavior, chaotic dynamics is incorporated into the proposed search algorithm. A chaotic Levy
flight is firstly incorporated in the proposed search algorithm for efficiently generating new solutions. And
secondly, chaotic sequence and a psychology factor of emotion are introduced for move acceptance in the
search algorithm. We illustrate the application of the algorithm by estimating the complete parameter
vector of a chaotic mobile robot.
