摘要
介绍了一种采用两步法进行位标器陀螺转子动平衡测量的数字方法。首先采用自适应数字陷波滤波器来进行频率的测量,然后采用线性最小二乘法来求出幅值和相位差的大小。两步的算法均为线性算法,具有收敛速度快、计算准确的特点。
A digital method for measuring dynamical balance of the coordinator gyrorotor is discussed. Two steps are applied to calculate the parameters of unbalance vibrating sinusoid. Frequency is first measured by an adaptive digital notch filter, then the linear least square method is utilized to compute amplitude and phase. The method has the advantage of fast convergence and high accuracy.
