Precision improvement for a tunneling accelerometer by using an intelligent controller to close its loop

The paper presents a way to improve the transient regime of a tunnelling accelerometer by using a fuzzy controller to close its loop. The fuzzy controller replaces an electronic amplification and filtering block of proportional-derivative (PD) type, used on the feedback path of the classical architecture. For the proposed controller, proportional-derivative variant is chosen, and its input-output mapping is derived. The membership functions both for inputs and output are triangular-shaped. To define the rules, a Mamdani fuzzy model is chosen. Finally, a comparative numerical study between the classical and the proposed accelerometer architectures is made.
