Disturbance rejection for structured systems

Abstract

The disturbance rejection problem for structured systems is solved. A graph is associated with such a structured system. Disturbance rejection is shown to be solvable by state feedback whenever the control inputs reach the outputs more quickly than the disturbances in the associated graph. The infinite structure of a structured system is characterized in terms of input-output paths in the associated graph.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
