The Distributed Spacecraft Attitude Control System Simulator: Development, Progress, Plans

چکیده
Virginia Tech has developed a testbed comprised of two independent spherical air-bearing platforms for formation flying attitude control simulation, the Distributed Spacecraft Attitude Control System Simulator (DSACSS). The DSACSS provides the flexibility to experimentally implement many types of control techniques. Novel individual platform control options include nonlinear compensation of an under-actuated system and coupled attitude control and energy storage techniques. Formation control schemes could consider integrated orbit and attitude control. Multi-actuator attitude control algorithms are being developed and tested on DSACSS, combining momentum/reaction wheel, control moment gyro, and thruster hardware. We are testing the effects of a moving baseplate on the performance of a magnetic bearing. The appropriateness of person-in-the-loop controllability is being investigated by linking DSACSS with Virginia Tech’s Cave Automatic Virtual Environment (CAVE). Further, the CAVE can be used to unify two testbeds — DSACSS and the Formation Flying Testbed at NASA-Goddard Space Flight Center — for complete formation flying experimentation. This paper provides details on projects using DSACSS.
