| Research Abstract |
We developed a digital controls system for the gravitational wave detector by an international collaboration with LIGO group in the U. S and installed it into a prototype gravitational wave detector CLIO located in Kamioka-mine. We implemented the system that able to control an actual complicated interferometer control topology by sensing and actuating signals digitally filtered and adjusted.
