Intelligent Control Strategy of Wind Curtain Type Anti-drift Sprayer Based on LSSVM Wind Speed Prediction and Fuzzy Control

In view of the problem of insufficient intelligence and precision in the current application of wind curtain type anti-drift spray application machinery, an intelligent control strategy based on least squares support vector machine wind speed prediction system and fuzzy control with intelligent wind curtain anti-drift system is designed. The system can effectively reduce the amount of pesticide liquid drift loss, make the droplet deposition distribution more concentrated, and improve pesticide utilization. Firstly, based on the analysis of the model of droplet drift deposition with bimodal distribution, the concentration and long tail of droplet drift deposition distribution are expressed by the bimodal deposition ratio and the tail length. Then based on the LSSVM, the mean wind speed in natural environment is predicted, which is an important condition for controlling wind curtain. Combined with fuzzy control strategy, the intelligent control system of wind curtain anti-drift system is formed. Finally, the effectiveness of the intelligent anti-drift spray system is verified by several experiments.
