The work focuses on the development of model and analysis of different control techniques for level process. The objective of this paper is to maintain the liquid level in a cylindrical tank at desired set value. The process is identified by step test. Based on the obtained model Ziegler-Nichols and Internal Mode control techniques are employed. The results are compared and the best among the two is validated. This comparative study is carried out and the best one will be highlighted with the help of time domain analysis
