Telescope Parallel Actuator Mount: Control And Testing, Samuel S. Artho-Bentz
Telescope Parallel Actuator Mount: Control And Testing, Samuel S. Artho-Bentz
Master's Theses
This thesis approaches the task of designing a control system for the Parallel Actuator Mount developed by Dr. John Ridgely and Mr. Garrett Gudgel. It aims to create a base framework that directly controls the telescope and can be expanded to accept external command. It incorporates lower priced components and develops more easily approachable software with great functionality. An open-loop method for velocity control is established. Developing repeatable tests is a major focus. Testing finds the control methods developed result in velocity error of less than 5% and position error of less than 1.5% despite several mechanical issues and inaccuracies. …

They operate loudly enough that users should be wearing hearing protection and the noise …
