Abstract�� For the sampled servo system using inductorsyn as position sensor, the presence of measuring delay leads to large measuring error. In order to solve the problem mentioned above, a new dynamic compensation method using linear extrapolation scheme was presented to compensate the measured output of inductorsyn. Thus the measuring error induced by measuring delay was reduced, and the system tracking precision was enhanced. By theory analysis, the bound of measuring error after error-correction was deduced. The simulation results and the experimental results applied to the three-axis flight motion simulator demonstrate its validity.
