Description

DECIGO (DECi- hertz Interferometer Gravitational wave Observatory) is Japanese space antenna project for detecting gravitational wave. One of DECIGO's technologies, "drag-free control", is the research theme. Drag-free control is to actively control the effects of external disturbances by tracking the satellite against a non-contact floating test mass inside the satellite in space. This research's final purpose is to ensure the 6-DOF drag-free control operation on the ground by constructing a ground-suspended demonstration system. Sensors mounted on the simulated satellite measure the distance to the test mass that is swinging in 6-DOF. And then, feedback is given to the actuator that drives the 6-DOF motion on the simulated satellite so that the distance between the simulated satellite and the test mass is kept constant. In this experiment, control of the Pendulum in a 2-D is demonstrated, along with 6-DOF sensing verification.
