Abstract:

I proposed new control method for KAGRA suspensions using recursive robust controller synthesis method as an adaptive control system. The motivation is to have a controller that can deal with drastic changes in the seismic noise which can cause lock-loss or high control noise introduction if improperly designed during gravitational wave observation.

Todo: Sections: Implementation plan, machine learning reinforced plan, generalization to all stages in VIS.
