Abstract: The main objective of this research work is to study the various conventional three mode controller algorithm for an interacting and non-interacting liquid level two tank system. For controlling any chemical process, a mathematical model is identified, suitable controller is designed and simulated to get the desired process behaviour. For this purposes, a lab scale interacting and non-interacting liquid tank system is considered. The mathematical transfer function model is obtained and various conventional PID controller algorithm are simulated, the efficiency of the methods are demonstrated in simulation using Matlab/Simulink software. The closed loop performance measure are calculated and tabulated. The simulation results shows that the conventional PID controller algorithm has good setpoint tracking and performance

Keywords: interacting system, non-interacting system, conventional PID, SISO system.
