Study of BAS-Fuzzy-PID Optimization on Water and Fertilizer Ratio System

In view of the limitations of the inaccurate waterfertilizer ratio in the traditional irrigation mode, this paper proposes a fuzzy PID controller optimized based on Beetle Antennae Search Algorithm to improve the water and fertilizer utilization efficiency. By constructing a simulation model with the concentration of water and fertilizer solution as the control object, the effect of the fuzzy PID controller optimized by Beetle Antennae Search Algorithm (BAS) in regulating the concentration of water and fertilizer solution is designed and verified. Regarding overshoot, the BAS-fuzzy PID exceeds the fuzzy PID by 26.9%, and its curve shows the most stable rise. The result shows that this scheme has advantages in improving the accuracy of water and fertilizer ratio and utilization efficiency.
