Design of a Nonlinear Finite-Time Converging Observer for a Class of Nonlinear Systems

[摘要] This paper proposes a nonlinear finite-time converging observer for a class of nonlinear systems. The estimate is recovered from the present and delayed estimatesprovided by two independent dynamical systems converging to a functionof the state with linear error dynamics. The estimation is carried out using onlythe Jacobian matrix of both transformations determined by solving two systems ofpartial derivative equations. The results are illustrated on a bioreactor model.
