RCS/Linear Discrete Actuator Study

Abstract:

The objective of the program was to develop the technology and demonstrate the use of linear discrete actuators combined with a rocket control system RCS to control the large angle slew and fine pointingtracking of a simulated large flexible space structure. The linear actuators included proof- mass actuators, and a hub torquer to simulate a control moment gyro or reaction wheel actuator. The demonstration used the CSDLAFAL ground test facility located at CSDL, Inc. The facility comprises the flexible test structure and actuators which are mounted on a low-friction, air-bearing table, and associated test instrumentation. The combined linear discrete and RCS actuators demonstrated significantly improved fine pointingtracking a vibration suppression capability relative to the uses of the RCS alone.
