The work describes the modeling, simulation and decentralized control of a coupled three tank system. The system is modeled mathematically using Bernoullie’s law, mass balance and energy balance. Then the model is simulated in MATLAB using script file and in simulink using S-Functions. This system is linearized using jacobian method form of mathematical model. The model is analyzed using Relative Gain Array (RGA). The controllers are designed and tuned iteratively using sequential loop closing (SLC). Controllers for flow are designed by specifying the closed loop response while PI controllers for temperature are tued iteratively. These controllers are also applied to non linear simulink model where they give a good stability and remarkable performance. Thus the PID controller for the height and temperature are also implemented in LabVIEW and the result shows good response.
