Then the optimal number of clusters is equal to 3 as it indicates in the 1 (Figs. 9 , 10
and Table 1 ).
The excitation signal must be rich to run the system in all operating region. In
order to reach all steps, the simulation results of the FCM algorithm are given by
the following Figs. 11 and 12 .
Algorithm FCM is followed the real data input of pressure and flow. It is noticed

that the error between the evolution of the real and estimated pressure is almost null
even for

fl

flow. The station of irrigation by sprinkling made up of two nonlinear
systems in the same way input and different output, one of pressure and the other of
fl

fl

flow, each one partitioned in 3 subsystems. We obtain the following results:
