Abstract:10cm。An autonomous navigation system based on self-adapted fuzzy control for agricultural tractor was proposed. PLC, electro-hydraulic switch valve and proportional directional control valves were used to construct the automatic steering control system based on PD control algorithm. A self-adapted fuzzy control algorithm was proposed, GA was adopted to optimize the fuzzy rules and proportion factor of fuzzy output online. It retained the advantages of conventional fuzzy control, and meanwhile, it improved the performance of autonomous navigation control system. Simulation and field experiment indicated that the proposed navigation control algorithm could eliminate the tracking error effectively with rapid response and small overshoot, the navigation system worked stably, the maximum tracking error was less than 10cm. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
