Abstract :
It is shown that in some situations the zero patterns of a flexible structure change radically with model order. The refinement of the model by the addition of higher-order modes can cause zeros to appear at low frequencies or in the right half-plane. Structures instrumented with piezoelectric actuators and/or fiber-optic sensors are also considered
