摘要
为解决经典的分子-电子感应式(molecular electronic transducer,MET)振动传感器系统机理建模复杂且与实际传感器特性存在差异的问题,提出Hankel矩阵和脉冲响应辨识相结合的方法对MET传感器进行了开环传递函数的结构和参数辨识。通过仿真分析验证提出的辨识方法的有效性。该方法快速有效,为提高传感器使用效率及后续信号调理设计提供了理论基础。
A new method which can identify the open-loop transfer the function of the classical molecular electronic transducer( MET)vibrating sensor was proposed. The transfer function identification method of the sensor was analyzed in order to overcome the complexity of mechanism modeling and the differences between the practical characteristics of the sensor. Method for realizing the parameter and order identification of the MET sensor was used by the Hankel matrix and the impulse response identification. The simulation and analysis showed that this method is fast and effective,and provides a theoretical basis for improving the efficiency in the use of sensor design and subsequent signal conditioning.
