Piezoelectric direct drive 3-axis highprecision gimbal
Charles Tschaggeny, M.S. University of Utah, January
2008
This projects designed, built, and tested a 3-axis gimbal whose three
rotational axes are actuated by a novel drive system: linear piezoelectric
motors whose linear output is converted to rotation by using drive
disks. Advantages of this technology are: fast response, high accelerations,
dither-free actuation and backlash-free positioning. The gimbal was
developed to house a laser range finder for the purpose of tracking
and guiding unmanned aerial vehicles during landing maneuvers. The
tilt axis was built and the test results indicate excellent performance
that meets design specifications.
