A new modal mode controlling method for a surface format surrounding mass accelerometer

A new model mode controlling method for a surface format surrounding mass accelerometer is presented. The controlling method can attain a stable feedback control without imposing a degree-of-freedom limitation on the sensor structure by using a multi-force balancing system. The controlling is based on the finite element method simulation result for the accelerometer structure and the fact that almost all vibrations occurring in the accelerometer in a normal vibrational environment can be expressed by a very small number of vibrational mode series. For this work, an application for the surface format surrounding mass accelerometer is presented as a demonstration.<>
