基于播种单体限深臂压力和角度的播深智能控制系统
An Intelligent Control System for Seeding Depth Based on the Pressure and Angle of the Depth-limiting Arm of the Seeding Unit
摘要
Abstract
In order to improve the stability and consistency of the planting depth of crops,and thus increase the yield of crops,a set of monitoring objects is designed,which takes the force of the depth-limiting arm on the depth-limiting block and the swing angle of the depth-limiting arm,and obtains the seeding depth information.The electric push rod is used as the executive element to adjust the up and down swing of the monomer.An intelligent adjustment system based on force feedback is studied.Through the mechanical analysis of the depth limit arm and the four-bar linkage,the range of the pressure sensor and the electric push rod is determined.Aiming at the problem of error in the operation of the electric push rod,the Mamdani fuzzy algorithm is used to establish an intelligent adjustment model to optimize the control of the electric push rod.The static test shows that adding the Mamdani fuzzy control algorithm to the control system can correct the peak value error of 75.6%,the control error of the seeding depth is reduced by 60%.关键词
