The Quadruple-Tank Process: A Comparison Among Advanced Control Techniques

Abstract:

A system composed of four tanks is presented for which it’s shown its mathematical model and the obtaining of different types of controllers considering that it has a multivariable system, so it is important to define the interaction between the input and output variables to choose the possible transfer functions on which to base the design of the controllers, or to design the decouplers and obtain the design base transfer functions with them. The results of the implementation of different designed controllers are going to be presented and their performance will be evaluated through indexes and transitory parameters such as its overshoot and establishment time. Based on all of this, the conclusion of this work are going to be presented as the better option to implement the control on this system and some considerations that have been shown in said results.
