Type-A Commissioning Tasks
Model
- Mechanical model : SUMCOM
- Electronics model and control loop model can be implemented in the Noise Budget tool
Existing suspension 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
