摘要：

An analysis of the solutions for various feedback control laws applied to vibrating cantilever beams is evaluated. The control is carried out via piezoelectric patch sensors and actuators. By considering an integral equation formulation, which is equivalent to the differential equation formulation, the analytical results are investigated. The conversion is accomplished by introducing an explicit Green's Function. The feedback controls implemented include displacement, velocity, acceleration and combinations of these. A numerical comparison of eigenvalues will be presented to illustrate the efficacy of the method and to contrast the effects of the controls. The results presented in the study can be used for benchmarking solutions based on numerical or approximation approaches.
