Stable Reduced Model of Linear Time Invariant System Using pole Clustering Method

Harendra singh singh, Ved Ram singh




A combined method for stable reduced order model has been proposed .In this method the denominator of reduced order model was obtained by formation of clustering of poles of original high order system (controller) while its numerator was derived based on time moments and Markov parameters. The clustering of poles of original high order system assured the stability of reduced order model if original system was stable. Proposed method was illustrated with the help of the numerical examples from literature.

Key words: Clustering technique, Reduction   order, Markov parameters, Stability, Time moments, Transfer function.
