Combination of Functional and Disturbance Observer for Positive Systems with Disturbances

This technique note proposes two classes of functional and disturbance observers for positive systems with structural non-structural disturbances, respectively. A observer is first proposed by introducing the estimation to observer. By developing technique, a designed supply in Then, new unknown input constructed systems. matrix decomposition method employed design gains. All conditions are described terms linear programming. The corresponding algorithms addressed computing presented conditions. Finally, examples provided verify effectiveness theoretical findings.
