The Feedback control system connected to a real time network through which the control process takes place are called network control system (NCSs).Features of NCS is the information like reference input, plant output, control input is exchanged between sensors, controllers, actuator using a network like CAN bus.The system wiring is reduced, easy to maintain and increases the system reliability.In the conventional control theories uses some ideal assumptions like equal distance sensing, synchronized control and non-delayed sensing and actuation.But in time varying systems this assumption fails due to transmission delay or packet dropout.In this paper Stability of NCS is analysed by considering transmission delay for a computer controlled system using scheduling algorithm
