基于模糊控制算法的智能风筛系统设计
Design of intelligent air screen system based on fuzzy control algorithm
摘要
Abstract
Objective:To solve the technical problems such as low separation efficiency,unstable control effect and overshoot in crop screening by air screen.Methods:An intelligent air screen system based on fuzzy control algorithm was proposed.The wind speed and the change rate of wind speed were designed as input variables,and the steering gear angle was taken as output variable.The angle of the steering gear was adjusted by fuzzy control rules to reduce the overshot of the screen,so as to improve the screening efficiency of crop impurities.Results:Through the system test,under the condition of 3 kg/s feeding amount and 11.7 m/s air volume,the impurity separation rate of air screen was more than 93％,no overshoot phenomenon,the designed fuzzy control algorithm was robust.Conclusion:The control system runs stably and can quickly adjust the angle of the screening plate based on wind speed,with high control accuracy and good control effect.关键词
