On the Dynamics of Two Mutually-Coupled, Electromagnetically-Actuated Microbeam Oscillators

The non-linear dynamics of electromagnetically actuated microbeam resonators with purely parametric excitations

Electromagnetic micro-transducers have been utilized in a number of distinct applications in recent years due, in large part, to their scalability, low power consumption, self-sensing capabilities and ease of integration with external hardware. In the present work, the highly non-linear dynamic behavior of a new class of parametrically excited, electromagnetically actuated microcantilevers is e...

A low-voltage three-axis electromagnetically actuated micromirror for fine alignment among optical devices

In this paper, a new three-axis electromagnetically actuated micromirror structure has been proposed and fabricated. It is electromagnetically actuated at low voltage using an external magnetic field. The main purpose of this work was to obtain a three-axis actuated micromirror in a mechanically robust structure with large static angular and vertical displacement at low actuation voltage for fi...

A Hybrid Systems Approach to Closed-Loop Navigation of Electromagnetically Actuated Satellite Formations Using Potential Functions

Potential function method has been used extensively to navigate robotic vehicles in the form of a closed-loop control law. One problem associated with the potential function method is the presence of local minima in the navigation space. This paper presents a novel approach of using switching in order to avoid the local minima and hence achieving global convergence to the desired configuration....
