Dither is a high frequency periodic signal that has been excunined in the literature before, for changing nonlinear systems effectively. The presented technique is based on a conjecture proposed by Genesio and Tesi and is mainly cipplicable to systems in Lur’e form. In the second part, the application of state feedback is presented. Unknown states of the system are constructed by using nonlinear full-state observers. The control strategy is mainly based on the mentioned conjecture and also on bifurcation diagriuns.ix, 51 leavesEnglishinfo:eu-repo/semantics/openAccessChciotic dynamicsdescribing function analysisditherobserversstate feedbackbifurcation diagramsQ172.5.C45 U49 1996Chaotic behavior in systems.Dynamics.Nonlinear theories.Thesis
