Abstract :
Great measurement errors can be made by the existence of measurement delay in sampling servo systems which use an Inductosyn as a position sensor. In order to solve the problem, a new dynamic compensation method is introduced to revise the measured output by employing linear extrapolation. In this method, the measurement errors are to be reduced, and the system tracking precision can be enhanced. Further more, based on theory analysis, this article sets a limit to measurement errors after making necessary revisions to the output. The method has been proved to be effective by both results of a simulated test and of an experiment conducted with a three-axis flight motion simulator
