Abstract

The paper shows how an accelerometer- enhanced velocity estimator can be used to improve the tracking performance of a feedback control system. In contrast to conventional velocity estimators that use positional information only, the accelerometer-enhanced velocity estimator fuses the position sensor and the accelerometer together to produce an improved velocity estimation. Experimental results are presented to show the effectiveness of the accelerometer-enhanced velocity estimator on improving the tracking performance of a linear motion stage.
