摘要
介绍了磁悬浮轴承的组成及其工作原理。分析了磁悬浮轴承的控制精度和可控转速两个重要性能指标与A/D转换器、传感器、功率放大器及控制算法之间的相互关系。以TMS32 0F2 4 0为核心设计了电磁轴承控制系统。实验结果表明 ,基于DSP的磁悬浮轴承数字控制系统具有稳定性好、响应快及低噪声等优点。
The composition and operational principle of magnetic levitating bearing are introduced. The correlation between two major specifications of magnetic Levitating bearing, i.e., control accuracy and controllable rotating speed, and A/D converter, transducer, power amplifier as well as control algorithm is analyzed. The electromagnetic bearing control system based on TMS320F240 is designed. The experimental result shows that the DSP based digital magnetic Levitating bearing control system features advantages of high stability, fast response and low noise.
