| Abstract: | The measurement error of the
torsional stress analyzer (TSA), in which the model-based simulation is used, is
discussed, and it is pointed out that the model error and the initial value error have
strong effect on the precision of torsional stress calculation. Based on the discussion, a
new method of torsional stress measurement using state observer is proposed, and it is
proved that the bad effects of model error and initial value error on stress measurement
can be reduced obviously through optimizing the feedback gain matrix of the observer. |
