Functional observer and state feedback for input time-delay systems

Local Observer Design For Nonlinear Control Systems Around Equilibria

“…Theorem 2 and Corollary 1 are for the classical case of nonlinear control systems with real parametric uncertainty, i.e., systems of the form (4) satisfying the assumption (14).…”

“…In [14], necessary and sufficient conditions were obtained for exponential observers for Lyapunov stable nonlinear systems and an exponential observer design was provided which generalizes the observer design of Luenberger [1] for linear systems. Krener and Kang ( [16], 2003) introduced a new method for the design of observers for nonlinear systems using backstepping.…”

“…For nonlinear control systems, the observer design problem was introduced by Thau ([2], 1973). During the past three decades, the observer design problem for nonlinear control systems has been studied extensively in the control engineering literature [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…In ( [14], 1997), Yao, Zhang and Kovacevic derived results for the design of state functional observer state feedback for systems with input time delays is addressed using the factorization approach in the frequency domain.…”

Delay identification in time-delay systems using variable structure observers

“…Several authors proposed observers (or predictors) for linear systems with delays (for the state space approach, see references in [5] and [3], for the coprime factorization technique see [40]; for the discrete time, see [37]), as well as the linear stochastic [16] and nonlinear [13] cases. An overview is given in [30].…”
