| Abstract: | The basic dynamic characters for the coupled dynamos system are analyzed by phase map, Poincare section, power spectrum and time series. It involves chaotic attractor, symmetry, equilibrium states and stability. In the case where the knowledge of goal states is not known, an adaptive feedback control is used to stabilize unstable steady states for the coupled dynamos system, and the academic provenance is given. Numerical simulations verify the validity and feasibility of the method. |
