Designand Research of Leveling Control System for the Flat Shovel of Laser-controlled Land Leveler for Paddy Field
摘要
Abstract
Plow leveling control of the flat shovel is essential for laser-controlled land levelers intended for paddy field work.This paper presents a low-cost design of leveling control system, among which their main features are:monitoring the plow’ s inclination by fusing one tri-axial accelerometer and one tri-axial gyroscope integrated in MEMS inertial sen-sor module ADIS16355.The makeup of the whole leveling control system, function of ADIS16355 and their installation on the plow are presented.On the base of level control system transfer function model established by its physical model, the nonlinear position algorithm was introduced with an implementation description on an ARMv7 processor Cotex-M3 , which was provided in terms of electronics hardware and software flowchart.Finally, test results showed that the proposed fusion method gives quite accurate inclination information of the plow and the whole leveling control system works relia-bly.关键词
