甘蔗切种机多刀闭环协同控制系统设计与试验
Design and Experiment of Cooperative Control System for Multi Blade Closed-loop Sugarcane Pre-cut Machine
摘要
Abstract
Aiming at the low seed cutting efficiency of the intelligent sugarcane seed cutter developed by our research group(hereinafter referred to as the intelligent sugarcane seed cutter),a multi blade closed-loop collaborative control system for the intelligent sugarcane seed cutter was designed and developed.In order to preliminatively verify the effective-ness of the system,a simulation platform of tool adjusting was built for experiments.The experimental results show that the average tool adjusting time of closed-loop control was 0.21 s less than that of open-loop control.The results of prototype test showed that:①When the motor pulse frequency f=6 kHz,the optimal speed of the tool adjusting motor was 120 mm/s,the absolute displacement error of the tool adjusting was less than 5mm,and the relative displacement error was less than 1%.When f>6 kHz,the relative displacement error was greater than 5%.When f≥8 kHz,the stepper mo-tor appeared serious blocking step,which affected the normal operation.②When the tool setting speed was 120mm/s,the closed-loop control tool setting time was 0.95 s/root,and the tool setting efficiency was improved by 74.32%.③Sugar-cane transfer speed increased by 50%to 0.15 m/s;Sugarcane transport distance increased by 80%and overall transport efficiency increased by 86.6%.④The qualified rate of seed cutting reached 98.02%,and the bud injury rate was less than 1%.Compared with the original system,the overall seed cutting efficiency of the seed cutting machine was increased by 83.20%,and the work was stable,realizing continuous and efficient automatic seed cutting to meet the actual produc-tion requirements.关键词
