摘要： In order to improve the water and fertilizer utilization efficiency, reduce the water and fertilizer losses, and address the shortcomings of traditional water and fertilizer irrigation systems, such as time-variance, nonlinearity, and poor adaptability, this study adopts water and fertilizer electrical conductivity (EC) as the controlled object to compare fuzzy PID control strategy optimized based on 12 kinds of swarm intelligent algorithms, PID, and fuzzy PID control. MATLAB/Simulink is used to simulate various swarm intelligence control strategies. It is observed that the fuzzy PID based on snake optimizer (SO) has the best control effect, with the lowest number of iterations being 22, fitness being 17.1, overshoot being 0.5601%, adjustment time being 3.13s, and the system response being relatively stable. Therefore, it is more suitable for the accurate control of EC in the intelligent water and fertilizer systems.
