DELGADO-AGUINAGA, Jorge Alejandro; OROZCO-MORA, Jorge Luis  e  RUIZ-BELTRAN, Elvia. Solution of the Decoupling Problem with a Fuzzy Proportional Controller of a Regular Parallel Pipelines Irrigation System. Ing. invest. y tecnol. [online]. 2013, vol.14, n.4, pp.523-536. ISSN 2594-0732.

This paper presents the design of a Fuzzy Proportional Controller (FPC) as a proposed solution of the decoupling problem without the mathematical model of the system and based only on error information and the physical principles of the system. The FPC is applied in a parallel piping system, which by its natural dynamic behavior is coupled, and with a suitable set of fuzzy rules (based on the error between the input and output), such that the system is decoupled. This system was chosen in order to care and optimize the use of the water due to the drought, climate change, and pollution that affects this vital fluid. It is also important to note that the decoupling problem has not been approached without a mathematical model as in this paper. The results are shown by simulations.
