State-of-the-art and Prospect on Sliding Identification and Control of Agricultural Machinery
Abstract:When agricultural machinery is driving in an agricultural environment, it is inevitable that common slip phenomena will occur and have obvious uncertainty. It has seriously hindered the development of agricultural machinery informatization and intelligence in planting, mid-tillage management and harvesting, which require precise operation. The current status of domestic and international research on sliding dynamics properties, sliding identification methods and path tracking control considering sliding were reviewed from three aspects, namely, sliding principle, sliding identification and traveling sliding control, respectively. Among them, researches about the sliding principle focused on the structural characteristics and driving ground environment of different steering mechanisms established by domestic and foreign scholars, and the models of various steering mechanisms and ground system were established. The sliding identification method was divided into two categories based on mathematical model and data-driven method, and the advantages and limitations of each method were discussed. Researches about the driving sliding control focused on the path following control method applied to agricultural machinery, and the limitations of the current driving sliding control were pointed out. Finally, it was pointed out that the research on driving slip detection was of great significance to the development of agricultural machinery automation, and it provided directional suggestions for the research on driving slip detection and control of agricultural machinery.Key words:agricultural equipment; driving sliding; path tracking control; sliding identification请点击“阅读原文”查看全文文件
