压力传感器动态性能分析与动态补偿

在对炮口冲击波测试中，压力传感器的动态性能指标是否满足测量要求至关重要。本文通过GLS(SF)方法建立压力传感器的数学模型，并由数学模型求出动态性能指标。然而该传感器的动态性能指标不能满足测量要求，针对此问题本文采用零极点相消的方法设计出动态补偿滤波器，明显提高了该传感器的动态性能，最终解决了该冲击波的测量问题。

Analysis and Calibration for Dynamic Characteristic of the Pressure Sensor

The dynamic characteristic of the pressure sensor is very important to the veracity of sensor in the pressure measurement of a certain gun. The modeling of sensor is established by the GLS(SF), a way of system recognition, and then is utilized to get the dynamic characteristic of sensor. Unfortunately, the dynamic quality of the pressure sensor cannot meet the measurement request. So the dynamic calibration filter is designed by the balance between zeros and poles to improve the dynamic characteristic of the sensor significantly. The problem is solved in the end.
