ISSO Y2005 Annual Report | Contents Real-Time Active Loading of Piezoelectric Ultrasonic Motors for
Simulating Space Robotics Applications • 61-63 Abstract--Piezoelectric ultrasonic motors (PUM) offer dramatic improvements in a variety of space-based robotics applications if the problem of real-time torque control can be solved. This research enhanced the UHCL PUM laboratory apparatus by the integration of a magnetic particle brake to enable real-time control of an active torque load. The implementation of real-time active torque load control permits the modeling of a variety of space-based robotics applications. It enables expansion of the performance database to include steady-state load behavior. |
