Book Description
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 pointing/tracking 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 CSDL/AFAL 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 pointing/tracking a vibration suppression capability relative to the uses of the RCS alone. Keywords include: Linear discrete actuators, Proof-mass actuators, and Flexible structure control. (rh).
