摘 要: In order to obtain high accuracy signals of displacement, a new displacement detection method for magnetic bearing based on DSP (Digital Signal Processor) was proposed. Therefore, a novel simple hardware circuit was designed, and an anti-aliasing filter circuit was equipped, which can solve problem of signals aliasing, and improve the anti-interference capacity of the system. In addition, a temperature compensation method based on the software was put forward to eliminate the temperature drift of displacement sensors. Finally, the effectiveness and reliability of the displacement dete system were verified in the experiment.

为了获得高精度的位移信号,提出了一种基于数字信号处理器(DSP)的磁悬浮轴承新型位移检测方法。为此设计了一种新颖且简单的硬件电路,并配备了抗混叠滤波器电路,可有效解决信号混叠问题,提升系统的抗干扰能力。此外,还提出了一种基于软件的温度补偿方法,以消除位移传感器的温度漂移。最后,通过实验验证了该位移检测系统在性能和可靠性方面的有效性。
