MARTINEZ-GUERRA, R. et al. Experimental Synchronization by Means of Observers. J. appl. res. technol [online]. 2014, vol.12, n.1, pp.52-62. ISSN 2448-6736.

In this paper we deal with the experimental synchronization of the Colpitts oscillator in a real-time implementation. Our approach is based on observer design theory in a master-slave configuration thus, a chaos synchronization problem can be posed as an observer design procedure, where the coupling signal is viewed as a measurable output and a slave system is regarded as an observer. A polynomial observer is used for synchronizing the Colpitts oscillator employing linear matrix inequalities. Finally, a comparison with a reduced order observer and a high gain observer is given to assess the performance of the proposed observer.

Keywords : Experimental synchronization; polynomial observer; reduced order observer; high gain observer; algebraic observability condition.
