Abstract :
We formulate a partial differential equation model for the ACTEX (advanced controls technology experiment) structure. The model takes the form of six one-dimensional Euler-Bernouilli beam equations. Two equations are used for each beam to model the transverse deformations in the local coordinates. Our model includes the passive and active contributions from the piezoceramic actuators and sensors in the internal and external bending moments. The results of the comparison of the ACTEX experimental data with simulation studies based upon our model are discussed
