Model order reduction of LTI system using Routh stability array method

Stability Analysis of a high-order system (HOS) is very complicated, tedious and costly. It creates a great challenge for an analyst to reduce those high-order problems into the lower order with some mathematical methods. In this paper, four complex linear time higher order problem on SISO system solved by using one of Mathematical method is known as Routh stability array method. The simulation result of proposed method compared with method used in literature, which gives the better results and system remain in a stable state with the least amount of time-consuming than the original HOS. RSA-MOR method executed an accurate, simple and effective result in any type of real time method used in this paper for comparative studies.
