中文摘要:在改进磁悬浮开关磁阻电动机传统径向力数学模型的基础上,针对其转子径向位移存在非线性、强耦合的特点,采用反馈精确线性化方法进行了动态解耦和完全线性化设计,实现了两自由度上转子径向位移的独立控制,并对解耦后的独立线性子系统采用滑模变结构控制方法进行综合。仿真结果表明,系统具有优良的解耦性能,而且和传统PID控制系统相比,滑模变结构控制系统具有优良的动态特性和鲁棒性。

Abstract: Improving the conventional radial force model for bearingless switched reluctance motor,feedback exact linearization method was applied to decouple and linearize rotor's radial displacement on two degrees of freedom. Sliding variable structure control method was then applied to synthesize the independent linear subsystems coming from decoupling. The simulation results showed that the designed system has excellent decoupling performance, and the system has better dynamic performance and stronger robustness than conventional PID control 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.
