N2 - This work describes the modeling, simulation and decentralized control of a Coupled Three Tank System. The system is modeled mathematically using Bernoulli'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 Control and Estimation Tool Manager from Simulink model and using Jacobian method form mathematical model. The model is analyzed using step response, eigen values, real part of poles, number of Right Half Plane (RHP) zeros, Relative Gain Array (RGA) and controllability. 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 tuned iteratively. These controllers are also applied to nonlinear Simulink model where they give a good stability remarkable performance.
