In this paper, an attempt has been made to design observer for Networked Control System (NCS) with random delays. The NCS has been modeled as a Hammerstein system, a cascade combination of static non-linearity and LTI system. Luenberger Observer and Kalman Filter have been used to estimate the system states. Simulation results have been presented which result in stable overall Hammerstein systems, with improvements over existing control procedures.Keywords: Networked Control System, hammerstein system, observer
