| 摘 要： | 针对单个电磁永磁混合悬浮系统的特点，建立其数学模型，采用两级串联的悬浮控制器对其进行控制，并对整个控制系统进行了动态特性的仿真分析和研究。分析结果表明：电磁永磁混合悬浮系统的悬浮刚度与间隙反馈系数减正比，悬浮阻尼不仅与间隙反馈系数减正比，而且也与间隙变化速率反馈控制系数成正比。从而为电磁永磁混合悬浮控制系统的设计和开发应用打下了一定的基础。

| Abstract: | According to characteristics of the controlled-PM maglev systems, its mathematic model was built and two series controllers were used to control it. At the same time, the dynamic characteristics of the whole control system was simulated and studied, The analytical results show that the suspension stiffness of the controlled-PM maglev systems is positively proportional to the feedback coefficient of air gap, and the suspension damping is not only positively proportional to the feedback coefficient of air gap, but positively proportional to the feedback coefficient of air gap derivative. Therefore, the foundation of the design and development of the controlled-PM maglev control systems is built. |
