本文以动圈式速度传感器为例,采用间接测试方法,不需要复杂和精密的测试设备,而发挥计算机迅速处理和计算的能力,用谱估计和参数估计两步算法,估计出速度传感器的灵敏度、自振频率、阻尼系数、电阻和电感等物理参数。本文所介绍的方法和算法具有普遍性,而且可用于其它常见的机电和电子系统动力学参数测试和估计中。 In this paper, a dynamic sensor is taken as an example. The indirect test method is used to estimate the sensitivity of the speed sensor by using the two-step algorithm of spectral estimation and parameter estimation, without the need of complex and sophisticated test equipment. , Natural frequency, damping coefficient, resistance and inductance and other physical parameters. The methods and algorithms presented in this paper are universal and can be used in other common electromechanical and electronic system dynamics parameters testing and estimation.
