Abstract

The main purpose of this work is to study the dynamic effects of a piezoelectric accelerometer in an active vibration control system. The analysis is focused on the stability based on Nyquist stability criterion. This is done by deriving the overall open-loop system transfer function for a single-degree-of-freedom system which includes the sensor dynamics into the equation. The polar plot results show that the system is only unconditionally stable for acceleration, but is conditionally stable for velocity and displacement feedback control.
