Abstract: Continuous Variable Feedback Synchronization(CVFS) algorithm is a simple control method for the synchronization of chaos. However, the adjustment of the feedback value in CVFS algorithm is very difficult. In order to solve this problem, a new algorithm named FGACVFS, which combined fuzzy genetic algorithm (FGA) with CVFS is proposed. The simulation result show that the a djustment of the k_ii (the elements in feeback matrix) is very convenient and efficient.
