Pole Clustering-based Modified Reduced-Order Model for Boiler System

ABSTRACT

A modified reduction order is proposed for the LTI boiler system from the pole clustering method to reduce the higher-order system which yields an exact system model also to minimize the complexity involved in traditional methods. This approach is used to compute the reduced-order system from the combined method of cluster and Routh-Padé approximation techniques that are to achieve the effective formulated reduced-order system, and the method is explained through a numerical example. To evaluate the higher-order system from the new technique, the results of the proposed method are compared with other recently developed order reduction techniques like pole clustering, optimization algorithm, minimum variance, least square and recursive least square. The comparison results show that the proposed method is a powerful and stable method for linear time invariant boiler system.
