Tillage Depth Control of High Horsepower Tractors Based on Position-Force-Sliding of Main-Secondary-Least Grading
摘要
Abstract
Aiming at the problem that existing tillage depth control methods cannot simultaneously consider multiple con-trol factors,a tillage depth control method based on position-force-slidingof main-secondary-least grading was pro-posed.This method combined three factors that affect the uniformity of tillage depth into three control loops.The control factor of the main control loop was the position factor,and the main control loop was used to directly control the actual height of the suspension mechanism,thereby achieving the purpose of adjusting tillage depth.The control factor of the secondary control circuit was resistance factor,while the control factor of the least control circuit was slip rate factor.The secondary control circuit and the least control circuit achieved indirect control of the suspension mechanism through multi-level adjustment of the PID controller control parameters in the main control circuit,thereby achieving graded adjustment of the plowing depth.This control method fully utilized the composite interaction between multiple factors by dividing the main,secondary,and least components of the control circuit,thereby achieving the goal of improving the uniformity of tillage depth.The experimental results showed that the uniformity of tillage depth using this method was significantly better than PID control,and the slip rate had also been improved to some extent.关键词
