Abstract

When large area piezoelectric sensors are used for structural control, they can exhibit a `hydrostatic' response due to external acoustic sources. This portion of the sensed signal leads to a response much like controller limit cycling if induced-strain actuators are used, because induced-strain actuators have no control authority over the hydrostatic response. Experimental results are shown for a large area PVDF sensor applied to a Bernoulli-Euler plate that demonstrate response to both the structure's strain field and an exogenous acoustic disturbance. Implications for structural and structural/acoustic control are discussed.
