Abstract |
|
Flow control in a conical tank is a highly nonlinear process due to variation of cross sectional area of tank with height. This is due to relationship between controlled variable, flow and manipulated variable, flow rate, which has a square root relationship. Conical tanks find wide applications in process industries. Their shape contributes to better dispersal of solids, when mixing and provide more complete drainage, especially for viscous liquids. This paper proposes different tuning methods of PID controller for a flow process. Four different controller tuning methods are taken. They are closed ZN method, modified ZN method [without overshoot], Internal Model Control Method and Model Predictive Control method. These four methods are compared and listed out in a table. Among these MPC method is the best tuning method of PID for a Flow process. |
