Title:
RECOILLESS DEVICE AND DIRECTIVITY CONTROL MIRROR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/131472
Kind Code:
A1
Abstract:
This recoilless device comprises: a base part; a drive mechanism that drives a first movable part with respect to the base part; a reaction mass drive mechanism that drives a second movable part with respect to the base part; a first relative position sensor that measures the relative position between the first movable part and the base part; a second relative position sensor that measures the relative position between the second movable part and the base part; a first control system 11 that controls the drive mechanism by taking in, as a feedback signal, a signal that is outputted from the first relative position sensor with respect to an inputted command value; and a second control system 12 that controls the reaction mass drive mechanism by correcting the command value with a correction parameter that adjusts the difference between mass properties of the drive mechanism and mass properties of the reaction mass drive mechanism, and taking in, as a feedback signal, a signal that is outputted from the second relative position sensor.
