Modeling and Control of a Viscoelastic Piezolaminated Beam
نویسندگان
چکیده
Modeling and control of a viscoelastic beam are considered. Piezoelectrical elements are bonded to the beam and used as actuators. The beam is also equipped with a strain gauge that serves as a sensing device. The beam system is described by the Euler-Bernoulli beam equation, which is Fourier transformed and numerically solved in the frequency domain. Then, two different approaches are evaluated to approximate the infinite-dimensional system with a low order parametric approximation. Finally, LQG control theory is applied to control both strain and transversal vibrations. Especially, the control of the strain shows promising results. Copyright c 2005 IFAC

متن کاملDynamic Response of an Axially Moving Viscoelastic Timoshenko Beam
In this paper, the dynamic response of an axially moving viscoelastic beam with simple supports is calculated analytically based on Timoshenko theory. The beam material property is separated to shear and bulk effects. It is assumed that the beam is incompressible in bulk and viscoelastic in shear, which obeys the standard linear model with the material time derivative. The axial speed is charac...
