JIC_V4_N2_RP3 Deepak Gupta Awadhesh Kumar Journal on Instrumentation & Control Engineering 2321 – 1148 4 2 14 20 Balanced Truncation, Singular Perturbation Method, Reduced Order Model (ROM) Model Order Reduction (MOR) is one of the important methods to reduce the order of large scale dynamical system which come in account from previous few decades. Here, the authors inspect one of the simple and efficient methods of MOR which is Balanced Realization, and it is further divided in to two methods of MOR, among them first one is the Balanced Truncation method and second one is the Balanced Singular Perturbation Approximation method. In this paper, the authors consider three examples of real time dynamical system namely, Building Model, Partial Differential Equation Model and CD Player. Both the methods have been applied on these models and an exhaustive comparison has been made. The authors consider both the Single Input Single Output (SISO) and Multiple Input Multiple Output (MIMO) system and have applied in the above examples.
