Abstract

The objective of this paper is to show the energy utilization of actuator and its performance in nonlinear process. Objective includes design and comparison of modified smith predictor, modified back calculation methods and conventional PI controller for conical tank level process (FOPDT). The design comprises of mathematical modeling of conical tank using two-point method, controller tuning and architecture of the process. In FOPDT models integral term influences the actuator to react beyond its limits which results with windup phenomena in the process. This can be controlled by limiting integral term with respect to actuator requirements. Whole experimentation is classified into three operating regions and for all the methods mentioned in the paper. Based on operating region the methods has their own significance in performance. The design approach has been validated through the real time results.
