摘要:
现有的电化学氢气传感器其温度特性不太理想，传感器输出的灵敏度与零点值随温度的变化发生漂移，测量精度不高，误差较大，因此需对其进行温度漂移补偿。基于最小二乘法改进了一种多项式曲线拟合方法，通过一定的条件约束和工程估算，得到一种温度漂移补偿算法。利用该算法对不同温度下的实测数据进行处理，极大改善了环境温度变化对系统输出的影响，通过理论数据和实测数据验证了算法的有效性和可行性，并用于工程实践。
Abstract:
The temperature characteristics of the existing electrochemical hydrogen sensor are not ideal. The sensitivity and zero value of the sensor output drift with temperature changes. The measurement accuracy is poor and the error is large. Therefore, temperature drift compensation is required. A polynomial curve fitting method is improved based on least square method, and a temperature drift compensation algorithm is obtained through certain conditional constraints and engineering estimates. The algorithm is used to process the measured data at different temperatures, which greatly improves the influence of environmental temperature changes on the output of the system. The effectiveness and feasibility of the algorithm is verified by theoretical data and measured data, and it is used in engineering practice.
