MODELLING AND REAL TIME CONTROL OF TWO CONICAL TANK SYSTEMS OF NON-INTERACTING AND INTERACTING TYPE

Abstract

Nonlinear process control is a difficult task in process industries. Real processes often exhibit nonlinear behaviour. Many process industries use conical tanks because of its shape contributes to better drainage. Conical tanks are used widely in leaching extractions in pharmaceutical and chemical industries, as well as in food processing industry. It is a kind of multiple-use equipment, designed for boiling and extraction working procedure. So control of conical tank presents a challenging problem due to its non-linearity and constantly changing cross section. In this project work of the mathematical modelling of Single Conical Tank, Two Conical Tanks of Non-Interacting type System and Two Conical Tanks of Interacting type System is designed and the responses of the processes are obtained. To control level in all the above categories, tuning of controller parameters are determined by Ziegler-Nichols (Z-N) tuning method. After proper tuning by Z-N method, conventional PID controller is applied to the above three categories and their responses are analysed both by MATLAB simulation and by real-time.
