摘要
针对传感器信号中存在的非线性误差,对采用软件校正的特点和实现方法进行了研究。文中详述了将最小二乘曲线拟合方法应用于传感器非线性校正的方法和优缺点,并提出了将最小二乘曲线拟合与线性插值相结合的方法,最后,通过一个工程实例描述了在实际工程中利用曲线拟合实现传感器非线性补偿的过程。
Methods of comprehension for non-linear error in signals of sensors based on software are introduced. Through least square fitting, the error is greatly reduced, and the precision of the system is further improved. Finally, through an engineering example, the process of implementing the compensation for the non-linear error in sensor is described by using curve-fitting in engineering practice.
