Static coupling is one of the most important factors affecting the measuring accuracy of three-axis force sensor. For the phenomenon of coupling, this paper introduces the principle of three-axis force sensor’ s couple. Analysis of two different linear decoupling algorithms, which were based on the Cramer theorem and the least square method. The static decoupling algorithm based on coupling error modeling is improved. Processing the data in the coupling direction using Newton’ s cubic interpolation method. The experimental results on the self-developed three-axis wrist force sensor show that the novel algorithm has high precision.
