阐述了一种基于模糊补偿的离散全局滑模导航控制方法。为了提高农用车辆自动导航的精度和稳定性,引入滑模变结构控制方法,并对其进行了改进。为了降低系统的抖振,采用模糊规则,对补偿控制量进行有效的估计,以消除不确定项的影响。仿真实验表明:该方法优于传统的离散的滑模控制,在理论上是可行的。
闡述瞭一種基于模糊補償的離散全跼滑模導航控製方法。為瞭提高農用車輛自動導航的精度和穩定性,引入滑模變結構控製方法,併對其進行瞭改進。為瞭降低繫統的抖振,採用模糊規則,對補償控製量進行有效的估計,以消除不確定項的影響。倣真實驗錶明:該方法優于傳統的離散的滑模控製,在理論上是可行的。

An autonomous navigation system based on sliding mode control for agricultural tractor was proposed.Sliding mode variable structure control method was introduced to improve the precision and stability of the agricultural vehicle au-tomatic navigation.In order to reduce the chattering problem of the system.Fuzzy rules were used to estimate of the a-mount of compensation control effectively to eliminate the influence of the uncertainties;the simulation experiments show that the method is superior to the traditional discrete sliding mode control.It is theoretically feasible.
