Dynamic compensation improves accelerometer measurements by correcting for system bandwidth limitations. This study extends a probabilistic method to second-order systems, significantly enhancing performance in dynamic conditions.
Area of Science:
- Measurement Science
- Signal Processing
- Control Systems
Background:
- Dynamic compensation addresses bandwidth limitations in measurement systems.

A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...
