Progress report
Type-A (Takahashi)
Past week report
Updated the Real-time model & medm for the Type-A payload.
The direct feedback paths from TM OpLev to the upper stages are reimplemented.
- The generic feedback path (OLSERVO, so-called band-path comb paths) updates:
- Driving matrices have been separated for each of local-based and global-based signals.
- Decoupling matrices for the photo-reflective sensors have been prepared.
- The diagonalization of these matrices is not implemented yet. We'll do at the moment of necessity.
- DAQ channel reduction is reflected on the current running models.
We found that the DAQ assignment on the channels TM_OPLEV_TILT_(PIT/YAW)_OUT is accidentally disabled. -> recovered.
- The messy overview screen was rearranged.
- Damping filter implementation on the payload is ongoing.
- Study on the deformation of base plate in the GAS filter with the ATC staff.
