Introduction
MEMS accelerometers have the merits of low power consumption, high sensitivity and small size [1].
Let us define the 3-axis accelerometers output , Figure. 1.
and the acceleration vector, which is expressed in the 3-axis accelerometers local referen-ce system (Fig.1). is the true acceleration in each axis.
The ultimately model of 3-axis accelerometers is given by: (1) Where ,.
