Abstract
With the development of MEMS technology, the industry related to micro-sensor has been growing constantly. Meanwhile, the integrated sensor is more demanding than ever before, and one of them is the integrated multifunction sensor. Nevertheless, due to the introduction of MEMS technology, the design rules of sensor has been changed, which include the acquisition rules of micro mechanical stress, the rules of small capacitance measurement, temperature drift, the relationship between micro mechanical displacement and natural frequency, the order of noise effect and the final noise bottom line etc. All these problems may cause the difference between the MEMS sensors’ device index and application requirements, which should be solved during the research of MEMS sensor technology.

应用于液压泵的 MEMS 复合传感器的建模研究
摘要
随着MEMS技术的不断发展,微传感器产业得到了快速的发展壮大。同时,人们对 集成传感器的要求也越来越高,集成式多功能传感器也成了一种不断增长的需求。而事 实上由于MEMS技术引入,传感器的相应设计规则也发生了变化。这其中包括:微机械 应力的获取规则、微小电容检测的规则、温度漂移的引入规则、微机械位移和固有频率 的关系、噪声作用的顺序、最终噪声底线等。这些问题导致制造出来的MEMS传感器器 件指标总是与应用需求有一些差距,需要在研发MEMS传感器技术的同时逐步加以解 决。
Aiming at the integrated sensor measurement, temperature compensation and fault diagnosis, the paper adopts the black-box modeling method of Support Vertor Mechine to design the algorithm of temperature compensation and fault diagnosis. Finally, the paper conducts the experiment based on the algorithm of temperature compensation and fault diagnosis to verify the validity and feasibility of the algorithm and provide a general solution for the standardization and measurement of this kind of integrated sensor.
