摘　　要：三维力传感器由于机械结构、制作工艺等方面的原因,一路信号的输入会对各路输出通道发生作用,产生维间耦合。维间耦合的存在是制约传感器测量精度的一个重要因素,为了将耦合干扰的影响降到最低,使用解耦算法对三维力传感器进行解耦成为了研究热点。本文研究了全回归法的线性解耦算法在三维力传感器上的应用,并与基于求广义逆矩阵的线性解耦方法进行了比较,结果表明前者比后者具有更高的精度。Due to the mechanical structure and manufacturing process of three-axial force sensor,the input of one signal will aff ect each output channel,resulting in dimensional coupling.The existence of coupling between dimensions is an important factor to restrict the measurement accuracy of the sensor.In order to minimize the infl uence of coupling interference,decoupling algorithm has become a research hotspot.This paper studies the application of the linear decoupling algorithm of the total regression method in the three-dimensional force sensor,and compares it with the linear decoupling method based on the generalized inverse matrix.The results show that the former has higher accuracy than the latter.
