Title
Stable Approximation Of Discrete Interval Systems
Abstract
The prime motive of this research article is to construct a new mathematical approach for approximation of higher-order discrete interval system into its corresponding lower-order discrete interval model (LODIM). In this approach, a stable approximation technique for discrete interval system is derived with the help of integrated derivative technique. The key feature of this approach is that it is eliminating both the reciprocal transformation and normalization process as carried out in existing methods. Additionally, it assures stability retention of LODIM and upholds the steady-state value of original system. In order to show the accuracy and effectiveness of the proposed approach, a standard sampled test system is taken from the literature. The proposed technique is compared with the recent and relevant techniques of model order reduction. Further, step response and Bode diagram are plotted to prove the efficacy of proposed approach. A comparative study is also undertaken to conclude the same.
