| 摘 要： | 为了设计最佳控制参数对两级磁悬浮运动系统进行稳定可靠的悬浮控制,运用动力学时域和频域分析理论对系统进行分析.经理论推导将系统差动式结构电磁力模型等效为质量-弹簧-阻尼二阶系统.并运用ANSYS软件对等效模型进行刚度和瞬态响应分析,由仿真结果确定了系统最佳等效刚度和阻尼比,并以此为依据设计系统PID控制参数?在仿真分析指导下,经反复调试,实现了两级磁悬浮运动平台的稳定可靠悬浮.实验结果验证了理论研究和仿真分析的正确性.

| Abstract: | The kinetic theory is used to analysis the two-stage maglev system and to optimize the control parameters. The magnetic force of differential magnet coil is considered as a mass-spring-damping second-order system,and analyzed by the software ANSYS. The equivalent stiffness and damping ratio of the system are designed according to the result of transient response and stiffness analysis. PID parameters are also designed theoretically. The maglev system works stably after repeated tests,and experiment result s... |
