Hello, ROD san.

Customer (Mr. OKUTA) asks me that ;
As for earthquake test, if they use 469 Digital Controller, displacement
feedback is pretty good compared with displacement desired, but,
acceleration feedback is not good (spike noise) compared with
acceleration desired, and, on the other hand, if they use STEX,
acceleration feedback is pretty good compared with acceleration desired,
but, displacement feedback is not good (amplitude is too small) compared
with displacement desired. If they wish that both signals (acceleration
& displacement) are matched, do we have any solution ?

Customer wants to use STEX rather than 469D because acceptance test data
showed that STEX results were better than 469D results. But, if they use
STEX, displacement is too small.
Do you have any idea to match both signals ?
