Kharitonov based Reduction of Interval systems using Cauer-second form and Mihailov Criterion

The simplification of higher-order interval system is implemented by applying the Cauer-second form and Mihailov criterion with the Kharitonov theorem. If the system is stable, the suggested method produces a stable reduced-order model. An example is solved to show the effectiveness of the technique. The responses show a close approximation of a higher-order system with the suggested reduction method. Further, comparing performance index and time domain specifications with recent methods validate the efficiency of the proposed approach.
