A Robust DSP Integrator for Accelerometer Signals
IEEE Transactions on Biomedical Engineering
The need for an accepted method for determining position data from digital accelerometer readings with known frequency range is very important. The method of this paper uses spectral information and provides more stability and accuracy than classic methods for the DSP case. It even reduces to a classic method for the nonoscillatory case. Examples show the robustness of the method, overcoming the instability apparent with other integration methods.
