Tracing control of chaos by driving the implanted parameter

We have effectively implemented the study of the tracing control of space-time action for the controlled chaotic system, which concerns the orderly change of dynamical feature, using the gradual change method for driving parameter. Numerical simulation results show that the evolutional alignments of the chaotic system rely on the harmonious signal strength when change scope of the parameter is a large region. Some simulation results of space-time chaos have been obtained.
