A Design Report On A Servo Controlled Inertial Sensor Test Fixture, James B. Dowdle
Retrospective Theses and Dissertations
This report discusses the design of a servo controlled positioning system for remote control positioning of inertial sensors while under high acceleration test in a centrifuge. A rotating fixture and an electronic control panel was built for this purpose, with two modes of operation. The fixture can be positioned with an accuracy of 0.05 degrees and a resolution of 0.01 degrees, or it can be maintained in a constant velocity mode at rates from 1 to 16 degrees per second. The velocity loop was implemented as a phase locked loop, and the command rate is entered as a frequency - …
