Abstract

This article aims in bringing out the benefits of multiSensor data fusion in controlling vibrating modes of a piezoactuated beam, using multirate output feedback control namely, periodic output feedback control and fast output sampling control. The vibrating modes are measured by two homogeneous piezoelectric sensors. The states estimated from sensor outputs using information filters are fused using information fusion. The system output is computed from the fused states and it is used to generate the controller output. The performance of the controllers for the suppression of first two modes of vibration is evaluated through simulation and in real time. Improved closed-loop performance is obtained with data fusion.
