Full-order Observer Design for Descriptor Systems with Delayed State and Unknown Inputs

This paper concerned with the problem of full-order observer designs for a class of linear descriptor systems with delayed state and unknown inputs. First, this work focus on designing a full-order observer for the descriptor systems with delayed state. Then, an H_∞ full-order observer for such systems is proposed. Sufficient conditions for the existence of these observers are established and proved. Numerical example is given to illustrate the feasibility of the obtained results.
