= Type-A Commissioning Tasks = === Model === * Mechanical model : SUMCOM * * Electronics model and control loop model can be implemented in the Noise Budget tool * Existing suspension [[https://granite.phys.s.u-tokyo.ac.jp/svn/KAGRA/trunk/kagranoisebudget/Suspensions/|NB model]] * Implement a standalone NB model for Type-A first * Then integrate it into the IFO NB model === Sensor / actuator diagonalization === * Tower part is on going (a fair bit done already) * CRY part will start from now * VIS experts should join the work to expedite it === TF measurements === * Check the mechanical status of the suspension * Base for the control * Comparison against the model predictions === Damping control === * Except for ITMY, inertial damping is going to be completed * Integrated work with CRY and VIS is necessary * Modal damping for GAS (later ?) === Hierarchical control === * Procedure * Measure TFs from various stages to TM * Design blending filters to combine them * Iteration * Establishing a good suspension model is necessary in the filter design process * Inject seismic noise to make sure that no actuator saturate === Automatic operation === * Guardian * Currently fairly incomplete * We can get help from the Type-B team (Mark and Terrence) * Automatic health check * Status monitor
