An LPV rational order control model of an irrigation canal is derived from system identification
experiments. This model is experimentally obtained by using the described LPV fractional identification procedure. This procedure
consists of the identification of a rational order model in each operation point in an experimental test canal. Global LPV
model is obtained from polynomial interpolation of local model parameters. Validation results demonstrate that rational order
models are more accurate than integer order models. Therefore rational order control models have an important role to play in
management and efficient use of water resources.
