【摘要】 介绍了主动磁悬浮轴承系统的组成和基本原理。在建立单自由度主动磁悬浮轴承系统数学模型的基础上,分析了目前应用的PID控制器的不足,并提出了一种改进型PID控制器。仿真结果表明,这种控制器比目前应用的PID控制器有更优良的动态性能。更多还原

【Abstract】 The basic principle and constitution of Active Magnetic Bearing System are introduced. On the basis of a mathematical model with one degree of freedom, an improved PID controller for the system is put forward in contrast with the disadvantage of traditional PID controller. The result of simulation shows that the controller has more excellent performance than traditional PID controller.更多还原
