Abstract: 本发明公开了一种微机械加速度计及其校准补偿方法，属于加速度测量技术领域。可通过双边平行板式梳齿电容上施加偏置调谐电压的方式调节加速度计等效刚度，由于该梳齿电容静电刚度随位移变化，该加速度计也可工作在位置闭环状态。闭环参考位置校准是在调谐电压上引入一个带宽外校准信号，对位移等效电压进行解调滤波，得到位移扰动量，基于此通过反馈环路对参考位置进行补偿，直至位移扰动量降为零；等效刚度校准是在闭环参考位置上加入一个带宽内校准信号，对力平衡反馈控制信号进行解调滤波，得出表征加速度计等效刚度的电压信号，基于此建立刚度补偿闭环可维持加速度计等效刚度恒定不变。本发明有助于检测和抑制加速度计输出漂移。

Title: Sensor apparatus

IPC: G01D5/243
Filed: 1986-07-21
Granted: 1990-10-30
Abstract: ABSTRACT         Sensor apparatus which uses non-contacting, inductance coil sensors to transfer information about a parameter being monitored from a moving member to an indicator mechanically isolated from the moving member. The inductance coil sensors each have a stationary tank circuit and a movable tank circuit which are inductive-ly coupled to produce a double resonance curve for the stationary tank circuit.  The parameter is  sensed by a unit having inductively coupled components.  This unit is connected to the moving tank circuit to change the inductance of the moving tank circuit in accordance with changes in the inductive coupling of the sensing unit which, in turn, are dependent upon the parameter being monitored.  As the inductance of the moving tank circuit changes, the relative frequency, amplitude and phase characteristics of the resonance peaks of the stationary tank circuit change.  The degree of change of these characteristics is a measure of parameter.           In order to reduce or eliminate common mode errors, the sensing unit is arranged to develop oppo-sitely directed signals which are time multiplexed to produce difference signals.
