Abstract :
In this study a new type of state observer for dynamic systems containing non-linear polynomials is proposed. The stability of the structure and also the uniform convergence of the state estimates are analyzed. The simple and efficient algebraic criteria of Naslin normal damping polynomials permit synthesis of the parameters. A series of simulations illustrates the proposed developments based on a Van der Pol equation.
