Modeling, simulation and PID control of water tank model using MATLAB and Simulink

Abstract

Paper deals with the modeling and simulation of the real model of the water tank as a part of the process control teaching system PCT40. The mathematical model of the water tank was created and constructed in Matlab’s simulation tool Simulink. Then the steady-state and dynamic analyses were performed and showed us limitations and behavior of the system. The simple identification in Matlab with minimization of the square of the simulation error was also introduced. Lastly, the PID control in Matlab was applied for controlling the water level in the tank. The PID block in Simulink offers also tuning of the output response by the setting of the robustness and speed of the control. ©ECMS Mauro Iacono, Francesco Palmieri Marco Gribaudo, Massimo Ficco (Editors).
