中文摘要:根据转向系统的回正特性,针对现有的电动助力转向系统模型在回正控制中的不足,提出了新的回正控制算法。借助专家控制器,实现了不同转向状态下控制策略的变换,即将常规助力控制和回正控制算法结合,采用控制器的辨识算法和监督算法构成闭环系统,使转向行程判断准确,实时性好。在此基础上,设计了新型的试验台架,可以更好地模拟车轮转向过程。结果表明,采用该回正控制策略能获得较好的回正性能,同时提高了转向系统的稳定性。

Abstract:According to the return-to-center characteristics of a steering system and the deficiencies of an electric steering system model in the process of return-to-center, a new return-to-center control scheme was put forward. By dint of an expert controller, a control scheme that can convert in different steering state was realized. Based on above analysis, a new pattern of test-bed was designed, which could simulate the process of steering better. The results show that this control scheme can obtain excellent return-to-center performance and improve the stability of steering system.

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.
