Abstract
TUNING OF CONTROLLERS FOR REFERENCE INPUT TRACKING OF COUPLED-DUAL LIQUID TANKS
Prof. Galal Ali Hassaan*
ABSTRACT
The paper presents five controllers to control a coupled dual liquid tanks process. One controller (PID) from the first generation of PID controllers and four controllers (PD-I, PD-PI, PI-PD and 2DOF PI) from the second generation. Each controller is tuned and used to generate a time response for step input tracking with focus on the maximum percentage overshoot and settling time as time based characteristics for the control system. The best controllers to control the process are outlined after comparison of the control systems generated using the five controllers.
