POSITION MEASUREMENT BY MICRO-ELECTRONIC ACCELEROMETER

G. J. Stein, M. Šperka

Abstract

Relative displacement measurement by use of absolute acceleration measurement was attempted. A micro-electronic accelerometer, working on the servo-accelerometer principle was tested for this application. The results of extended investigation indicate that this theoretically simple way of relative displacement measurement is not feasible in practice due to large errors introduced by doubleintegration of the accelerometer output signal corrupted by drift and noise.
