This paper presents two control techniques to cater issues of stabilization due to network delays in the network control systems (NCS). First technique is focused on the modification a simple PI controller by adding a middle ware to adjust PI parameters in accordance with the delays. Next, a novel technique Automatic Disturbance Rejection Control (ADRC) is discussed to cater the issues due to delays. The ADRC stabilizes the response of the system however the overall response is delayed.
