Abstract

The control precision of the maglev system based on the force control should be evaluated by the dynamic performance of coupling system of multi-axis force sensor structure and its measuring circuits. The dynamical model of the coupling system is established in consideration of the dynamic characteristics of multi-axis force sensor structure and its measuring circuits. The amplitude-frequency curves of the coupling system are obtained through simulation, and its curves are modified in order to make coupling system get a better dynamic performance. The results show that under the action of excitations, amplitude error of the coupling system unmodified reach to 9% when the frequencies of the excitation are lower than 330 Hz, and its dynamic characteristics are poor; Amplitude error of the coupling system modified is less than 1% and the coupling system has a good dynamic performance which can meet the lossless measuring conditions.
