中文摘要:将模糊PID自适应控制方法应用到拖拉机电液悬挂系统控制中。根据系统特性,设计了模糊PID自适应控制器,建立了电液悬挂系统模型,并与普通PID控制方法进行了牵引力控制、位置控制性能仿真分析。搭建了试验台对电液悬挂系统进行田间试验。试验结果表明,采用模糊PID自适应控制以后,电液悬挂系统设定耕深由0.1 m阶跃至0.3 m时,系统过渡过程时间为4 s,无超调量;设定牵引力由3 kN阶跃至7 kN时,系统过渡过程时间为5 s,系统超调量为25%。

Abstract:Fuzzy-PID self-adaptive control method was used in tractor’s electro-hydraulic hitch system. Firstly, the fuzzy-PID self-adaptive controller was designed, and the model of the system was built. Secondly, the performance of draft control and position control was simulated and analyzed compared with PID control. At last, a field-test bed of electro hydraulic hitch system was built. The test result showed that fuzzy-PID adaptive control had a better performance than PID control in electro-hydraulic hitch system. When the preset position stepped from 0.1 m to 0.3 m, the response time was 4 s, and overshoot was 0. When preset draft stepped from 3 kN to 7 kN, the system’s response time was 5 s, and the overshoot was 25%.

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.
