Abstract: abstract:A model reference adaptive control approach, designed in the modal space, is applied for flutter control of a cantilever pipe conveying fluid. The control input is provided by a pair of surface-mounted piezoelectric actuators which are driven 180° out of phase to provide an equivalent bending moment acting on the controlled system. Comparison of performance of the model reference adaptive control with that of the optimal independent modal space control reveals that the former is more robust than the latter in terms of flow speed variations, which are unknown in the control system designed; that is, the adaptive approach can tolerate a larger range of flow speed uncertainties without resulting in an unstable control system, so that successful flutter suppression of the fluid-conveying cantilever pipe with high flow speed can be achieved.
