AI Technical Summary
Existing technologies cannot effectively solve the multi-source zero drift error caused by multi-factor coupling in magnetoelectric angular displacement sensors, including problems such as installation gap differences, zero bias voltage drift, and high-frequency noise interference.
A multi-stage fusion compensation method is adopted, including independent correction of Hall sensor signals, circular fitting geometric correction, and wavelet transform denoising, which are used to process different error sources respectively.
It significantly reduces multi-source zero drift error, improves angle measurement accuracy, with an improvement rate of 91.6%, meets the requirements of high dynamic working conditions, and ensures real-time performance and computational efficiency.
