Vibration control of piezoactuated cantilever beams using adaptive filtering

Adaptive filters play a major role in vibration control of piezoactuated cantilever beams. Though a variety of adaptive algorithms are available to suppress vibrations, recursive least square algorithm is used because of its faster convergence and better control performance. In this paper, the ARX based system identified cantilever beams and their parameters are considered for simulation. Results show that the vibration control of piezoactuated cantilever beams can be achieved using recursive least square algorithm on the adaptive IIR structure. With this algorithm, the percentages of vibration suppression of piezoactuated cantilever beams with different natural frequencies are observed.
