基于电感线性温漂特征的嵌入式拟合补偿算法研究
Research on an Embedded Compensation Algorithm Based on the Linear Temperature Drift Characteristics of Inductance
摘要
Abstract
An embedded fitting compensation algorithm is proposed in present study,so that to address the precision degradation in magnetoresistive position sensor caused by ambient temperature-induced drift.The algorithm leverages the resistance of the internal coil as a proxy to reflect real-time temperature parameters.By comparing these parameters with the calibration baseline and incorporating them into a lin-ear functional relationship between inductance drift and temperature variation,the inductance values are dynamically corrected to achieve robust temperature compensation.Engineering validation demonstrates that the proposed algorithm significantly enhances the detection accuracy of the sensor.Within the specified operating temperature range,the position detection drift is reduced to less than 0.15 mm,representing a 58％improvement in precision.The results indicate that the sensor exhibits superior environmental adapta-bility under fluctuating thermal conditions.关键词
