Optimal Observer Design of State Delay Systems

New Optimal Observer Design Based on State Prediction for a Class of Non-linear Systems Through Approximation

This paper deals with the optimal state observer of non-linear systems based on a new strategy. Despite the development of state prediction in linear systems, state prediction for non-linear systems is still challenging. In this paper, to obtain a future estimation of the system states, initially Taylor series expansion of states in their receding horizons was achieved to any specified order an...

H∞ Observer Design for Time-Delay Systems

A method for H∞ observer design for linear time-delay systems based on the algebraic Riccati equation is proposed. A ”weak” sufficient condition for the existence of such an observer is given.

Functional observer and state feedback for input time-delay systems

A State Observer for Nonlinear Delay Systems with Delayed Output

This paper presents an asymptotic state observer for the class of nonlinear dynamic systems with time-delay both in the dynamic equation and in the output equation. In previous works state observers have been studied only for nonlinear systems with delay in the state equation and without delay in the output equation and for nonlinear system with only output delay. Su±cient conditions are given ...

Observer design for linear singular time-delay systems

This paper investigates the problem of observer design for a general class of linear singular time-delay systems, in which the time delays are involved in the state and its derivatives, the output and the known input (if there exists). The involvement of the delay could be multiple which however is rarely studied in the literature. Sufficient conditions are proposed which guarantees the existen...
