Abstract

Control of process parameters are important in the chemical process industries. Proportional, integral and derivative controller is the most commonly used to form a closed loop system for the effective control of process parameter. In this paper, a liquid level in the cylindrical tank is to be controlled at setpoint value. At first, The model for such a real time process is identified and validated. To obtain the effective controller parameters settings, a conventional PID control model based PID were analyzed and the efficiency of the model based PID controller is highlighted with aid of time domain analysis. The ability of the designed model based controller in terms of tracking set point is also compared and simulation results are shown.
