Modelling the nonlinearity of piezoelectric actuators in active vibration cancellation systems using neural networks

Y Bissessur

Abstract


Piezoelectric actuators have great capabilities as elements of intelligent structures for active vibration cancellation. One problem with this type of actuator is its nonlinear behaviour. In active vibration control systems, it is important to have an accurate model of the control branch. This paper demonstrates the ability of neural networks to model the nonlinearity of a piezoelectric actuator in the control branch.

Keywords : Piezoelectric actuators, active vibration cancellation, system identification, neural networks.
