A Point Memory State Observer with Adjustable Parameters for a Class of Uncertain Linear Systems with State Delays

In this paper, we present a point memory robust state observer with time-varying adjustable parameters for a class of uncertain linear systems with state delays. The point memory robust state observer proposed in this paper consists of fixed observer gain matrices and time-varying adjustable parameters, which are determined by updating rules. Sufficient conditions for the existence of the proposed point memory robust state observer can be reduced to solvability of LMIs. Finally, simple numerical examples are included to illustrate the effectiveness of the proposed robust state observer.
