Nonlinear Systems, Adaptive Observer, Margin Parameter Variation, Robustness
In this paper, adaptive observer robustness is studies. The adaptive observer is proposed to a nonlinear system linearized by output injected for variable structure systems. Despites, the adaptive observer is suggesting to supply the parameter variation but it isn't usually verified. Unfortunately, the parameter uncertainty impact state convergence. For that a margin parameter variation is determined which the convergence of the state is guaranty. Simulation results show that the adaptive observer is robust only in the definite parameter margin variation.
