Abstract:
This paper presents a novel arrangement of Routh table array for deriving an approximate model
of a higher order z-domain uncertain system. The demand for this computation is to procure a
lower order model which is easy to be exercised in comparison to their original large scale systems.
Additionally, the derived model should preserve fewer dynamic characteristic of the comprehensive higher order systems. The mentioned new arrangement is achieved from the arena of different
combinations of numerator and denominator polynomials. The combinations are validated by their
practice over the conventional example from the literature. This precise blend is then applied to
a real-time system for its rational acceptability. Both the models play a significant role in establishing the algorithm. Besides this, the limitation encountered during the foundation course of
the arrangement is also taken into consideration. The paper also offers a future scope for fellow
researchers
