Linear-Like Discrete-Time Fuzzy Control In The Regulation Of Irrigation Canals, Ömer Faruk Durdu
Linear-Like Discrete-Time Fuzzy Control In The Regulation Of Irrigation Canals, Ömer Faruk Durdu
Turkish Journal of Agriculture and Forestry
A linear-like discrete-time fuzzy controller was designed to control and stabilize a single-pool irrigation canal. Saint Venant equations for open-channel flow were linearized using the Taylor series and a finite-difference approximation of the original nonlinear partial differential equations. Using the linear optimal control theory, a traditional linear quadratic regulator (LQR) was first developed for an irrigation canal with a single-pool, and the results were observed. Then a linear-like global system representation of a discrete-time fuzzy system was proposed by viewing a discrete-time fuzzy system in a global concept and unifying the individual matrices into synthetic matrices. This linear-like representation aided …
