| Abstract: | In this paper, the synchronization of a unified chaotic system is
investigated by the use of output feedback controllers; a two-input
single-output feedback controller and single-input single-output
feedback controller are presented to synchronize the unified chaotic
system when the states are not all measurable. Compared with the
existing results, the controllers designed in this paper have some
advantages such as small feedback gain, simple structure and less
conservation. Finally, numerical simulations results are provided to
demonstrate the validity and effectiveness of the proposed method. |
