Models with Accelerometers

Accelerometers are frequently used as structural sensors due to their simplicity, and because they do not require a reference frame. However, they amplify high-frequency parasitic noise. In this section we will discuss the modeling of structures instrumented with accelerometers. The acceleration output was not an option in the standard structural model, in the second order, or in the state-space model, cf. (2.7) and (2.35). In both models the output is composed of structural displacements and/or velocities.
