基于PID参数整定的低碎籽率联合收获机设计
Design for Combine of Low Seed Broken Rate Based on PID Parameter Setting
摘要
Abstract
In order to reduce the seed broken rate of combine , kernels on the feeding drum of axial flow type united har-vest machine is improved , the use of the PID regulator to adjust the screw propeller speed , using the fuzzy control princi-ple on the regulator parameter setting , so as to improve the control precision of the threshing process .In order to verify the improved the reliability of the whole feeding type combine , its function was tested , the test project mainly includes the response time and overshoot of fuzzy control , the broken rate of corn seed kernels under the test of fuzzy control is mainly use MATLAB SIMULINK toolbox to complete offers .By testing found that combine the speed of increase 1 rad/s, its control time is only 1 s, after fuzzy control overshoot volume reduced obviously , the response curve smoothing , adjust the time ideal , at last , it was found that the grain crushing rate using this article designed a low rate of grain crushing the united harvest machine in the process of harvesting grain crushing rate were significantly lower , comply with the design requirements .关键词
