摘要
Systems and methods for minimizing vibration rectification error (VRE) for a closed-loop accelerometer. In one embodiment, the method includes applying a known vibration signal to the closed-loop accelerometer along a first axis and adjusting a feedback gain setting until VRE is below a first threshold value. After the feedback gain setting has been adjusted, applying a random vibration signal to the closed-loop accelerometer along the first axis and adjusting a servo system proportional gain value until VRE is below a second threshold value.
