Proposed a new procedure for modeling of high order linear time invariant SISO Interval
systems. The numerator of reduced model is obtained by Cauer second form and denominator
was obtained by Eigen spectrum analysis. This method generates a stable lower order model
for a stable high order model. The reduction procedure is simple, efficient and computer
oriented. The algorithm is illustrated with the help of one numerical example to highlight the
advantages of the approach and the results are compared with the other existing techniques.
