In this paper, pole placement and stability behavior of reduced order model using Pade approximation method and Routh Stability Criterion by V. Krishnamurthy Method has been investigated. Higher order systems are reduced to lower order systems using Reduced Order Modelling (ROM) Techniques.In this reduction technique we here conclude that the shifting of the poles of original system and reduced system gives some important results about the Pade approximation unstability problem.. The results are compared with the Routh Stability Criterion by V. Krishnamurthy Method. Pade approximation and Routh stability criterion by V.Krishnamurthy methods are very good and simple methods of reducing a higher order system.
