Abstract: In this paper, the design and simulated results of conventional controllers on non linear hopper tank system are presented to attain a desired level of a process tank. The hopper tank non linear systems are used for this analysis which is also used in the field of Pharmaceutical, Petro chemical industries. Evacuation of products without wastage is possible due to non-linearity of hopper tank’s cross sectional behavior of the process. The open loop performance are determined to obtain the desired level control with conventional PI, PID controllers for various tuning techniques like step response based Ziegler Nicholas and open loop Cohen coon tuning method. The major advantage of this method is simplicity. The relationship between these two tuning systems is reproduced by Matlab Simulink model & Compared the presentation of controllers with hopper process tank.
