%X In this paper, adaptive observer robustness is studies. The adaptive observer is proposed to anonlinear system linearized by output injected for variable structure systems. Despites, theadaptive 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 parametervariation is determined which the convergence of the state is guaranty. Simulation results showthat the adaptive observer is robust only in the definite parameter margin variation.
