摘　　要：静电陀螺仪的稳速控制所需的转速信号是从包含多种信息的光电传感器输出中提取的,因此准确地提取转速信号是稳速控制的前提。文中分析了采用平面反射式光电传感器读取信息的静电陀螺的转速提取机理,讨论了自适应相干模板法滤除窄带干扰的原理,并将其应用到静电陀螺的转速信号提取中,在DSP(数字信号处理器)上得到实现。在某静电陀螺实验中得到了实时的转速信息,取代了原有的模拟系统,为数字化的稳速系统提供了可靠的参数。The rotational speed signal of ESG for stabilizing speed is picked up from the photoelectric sensor’s outputs which contain various kinds of information. The pick-up principle of ESG rotational speed was analyzed, in which a plane-reflecting photoelectric sensor was used to read information. The theory of using adaptive coherent model to filter narrowband interference was illustrated. Then the theory was applied to the ESG’s rotational speed pick-up and realized on DSP（Digital signal Processing）. The real-time rotational speed information was got in ESG experiments, and was used to replace the former analog system. This provides reliable parameters for digitalized stabilizing speed system.
