摘要

本文针对不同特性的InSb和GaAs器件设计了霍尔传感器的数学模型，并通过MATLAB仿真验证了两种模型的有效性。考虑到实际系统中用于补偿两个传感器的温度非线性的微处理器计算能力的限制，温度补偿的线性回归分为几个部分，并以一阶多项式进行。计算了线性回归拟合曲线与霍尔传感器数据之间的误差率。进行了性能评估，确认误差率在1%以内。

Mathematical models with temperature compensation for InSb and GaAs hall sensors using linear regression method

In this paper, we designed the mathematical models for InSb and GaAs devices which are hall sensors with different characteristics and confirmed the efficacy of the two models through simulation in MATLAB. Assuming the limitations on the computational capability of the microprocessor which will be used to compensate the nonlinearity due to temperature for the two sensors in the real system, the linear regression for temperature compensation is divided into several sections and performed in first order polynomial. The error rate between the curve fitted by the linear regression and the data received from the hall sensor was calculated. The performance evaluation was carried out and it was confirmed that the error rate was within 1%.
