A common problem in most irrigation systems during operation is pressure fluctuation. This issue is often neglected, but special measures must be considered to control and regulate it. The present research presents a method coded in MATLAB/mfile based on the use of variable speed pumps and pressure sensors installed at key points of the system to control and regulate pressure fluctuation. This method can predict and control causes of pressure fluctuations in the system and help to increase the efficiency of operation. The pressure sensors at key locations recorded pressure data over time. Dynamic planning using the data allowed decision-making to reduce fluctuations to continue pumping by transmitting information to the variable control drive through the program output. The results show that the use of this method in pumping stations equipped with variable speed pumps can reduce pressure fluctuations and optimize performance at the pumping station. The use of this method produced an RMSE index in the pressure fluctuation domain (±5% and ±10%) of 0.3 from a value of 0.9 before pressure control.
