Real Time Analysis of Two Tank Non Interacting System Using Conventional Tuning Method

This paper investigates the performance of Process Reaction Curve (Cohen Coon) and Ziegler Nichols tuning techniques based on PID Controllers for the control of liquid using two tank non interacting system. Initially, Cohen Coon tuning technique is applied and then to achieve further improvement in performance Ziegler Nichols tuning technique is chosen. It is observed that the Ziegler Nichols method gives satisfactory results than Cohen Coon tuning technique.
