AB  - Modeling physical systems usually results in system of higher order whose order is >2. Design of controllers for the working system becomes tedious when the system order is high. It is often desirable to approximate these models by reduced order models. In this study, a computationally simple approach is proposed for order reduction of linear time invariant discrete systems. The controller is designed for the reduced order model and is connected in cascade with the original system to obtain the desired specifications. The proposed method assures the stability of the system under the reduced order model case. The validity of the proposed method is illustrated by solving few numerical examples and the results are compared with the existing techniques.
