DESIGN OF CDM-BASED CONTROLLER FOR INTEGRATING PUMPED TANK PROCESS, ITS COMPARATIVE SETPOINT TRACKING PERFORMANCE, AND DISTURBANCE REJECTION CAPABILITY

Öz

Integrating processes are non-self regulating and very difficult to control. The pumped tank process is an example of such processes. In this paper, first of all, first order plus dead time (FOPDT) integrating model of the pumped tank process is obtained by a software called Loop-Pro Trainer. Next, the PI tuning values are computed using the internal model control (IMC) tuning correlations based on truncated (first-order) Taylor series approximation. Subsequently, a controller is designed using the coefficient diagram method (CDM). Eventually, the performances of the PI and CDM controllers are compared. It is concluded that if no overshoot together with a shorter settling time is required, the CDM-controlled system has advantageous performance, although  the PI-controlled system yields about 61% faster response as a percentage of the  CDM-controlled system.
