摘要
对力平衡加速度计的原理和在线测试方法进行了理论分析和实验研究 ,在工程实践中 ,依据加速度表系统数学模型的理论分析为基础 ,根据加速度表系统的具体线路 ,拟合出加速度表的系统开环传递函数。对系统进行在线测试并采用曲线拟合的算法 ,辨识出系统的数学模型。
A capacitive accelerometer using an electrostatic servo system was developed and analyzed. And the theory and method of in-circuit measurement is discussed. In the system, the math-model analysis of the accelerometer is the base for analyzing in practice. And in the accelerometer system development,dynamic signal analysis technology is used to measure the behavior of accelerometer system in circuit in frequency domain. The math-model of accelerometer system would be acquired with curve fitting by using system identification.
