摘要
针对数学模型在动态校准实验数据处理中的重要地位,结合激波管对压力传感器测试系统动态校准所得实验数据,介绍了一种基于广义最小二乘法的动态数学模型建立方法。并利用Matlab/Simulink模块进行了仿真验证,由仿真结果表明该时间域数据处理方法具有简洁性、准确性的特点,特别适合于动态校准中建立差分方程模型。
For the important role of mathematical model in data processing of dynamic calibration, a dynamic mathematical model based on generalized least squares method is defined, combining the experimental data from dynamical calibration of pressure sensor test system using shock tube. And Matlab / Simulink simulation module is used to simulate it and verify the result. The simulation results show that this time domain data-processing method has the characteristics of simplicity and high accuracy. It is quite suitable for establishing differential equation model in dynamic calibration process.
