Control of a Clamped-free Beam by a Piezoelectric Actuator

We consider a controllability problem for a beam, clamped at one boundary and free at the other boundary, with an attached piezoelectric actuator. By Hilbert Uniqueness Method (HUM) and new results on diophantine approximations, we prove that the space of exactly initial controllable data depends on the location of the actuator. We also illustrate these results with numerical simulations. Mathe...

Design and Simulation of a Clamped-Clamped Micromechanical Beam AM Frequency Mixer-Filter

In the last decade Micromechanical components for communication applications has been fabricated via IC-compatible MEMS technologies. In fact, its most important impact is not at the component level, but rather at the system level, by offering alternative transceiver architectures that reduce power consumption and enhance performance. In this paper a mixer-filter for AM frequency receiver with ...

Model for the Voltage and Charge Actuations of Deformable Clamped- Clamped Beams in Presence of Dielectric Charging

 Using the SEM analysis technique, we present the first direct evidences of the non-uniform distribution of charges trapped in the dielectric layer during the actuation of electrostatic MEM devices. We highlight the importance of the contact quality to control the charge injection in the dielectric. We further incorporate the non-uniform charge distribution in a 2D model of the actuation of de...

Dynamic response of clamped axially moving beams: Integral transform solution

The generalized integral transform technique (GITT) is employed to obtain a hybrid analyt-ical–numerical solution for dynamic response of clamped axially moving beams. The use of the GITT approach in the analysis of the transverse vibration equation leads to a coupled system of second order differential equations in the dimensionless temporal variable. The resulting transformed ODE system is th...
