Abstract
Modeling hydraulic systems for agricultural irrigation is critical to optimizing water usage and ensuring system reliability. This manuscript presents the development and validation of a dynamic hydraulic model using MATLAB/Simulink, constrained to technologies available up to 2015. The model simulates pump performance, pipeline flow, pressure regulation, and valve control under varying field conditions. A statistical analysis of simulation outputs demonstrates model accuracy against experimental data from a pilot irrigation setup. Key research objectives include quantifying flow stability, evaluating energy consumption, assessing pressure fluctuations, optimizing valve scheduling, and validating model fidelity. Simulation research covers steady-state and transient analyses, with results indicating that the Simulink-based model can predict system responses within 5% of measured values. Conclusions discuss implications for irrigation management and recommendations for further refinement.
