In this paper, we aim to analysis the system which contains time-delay elements including closed loop system and uncertainty. Time-delay will happen during the long distance communication. Therefore, when we have a control object in a long distance, the transmitted reference signal will be delayed certainly. For this reason even though we assume the control object system is a stable, but it will be an unstable system due to existence of time-delay elements. So, we consider the Internal Model Controller method which is one of the robust controllers. Internal Model Controller method is composed of optimum controller and uncertainty model of control object and time-delay elements. The optimum controller is designed by minimizing the coefficients of external disturbance of output signal by H^2 norm in order to stabilize the closed loop system considering the uncertainty of control object and predicted time-delay. Also, in order to compare the performance of the Internal Model Controller, we have compared with Linear Quadratic Integration method. As results the performance of Internal Model Controller was much better than the Linear Quadratic Integration method.
