Integrated Type-A control meeting
To Do
Model
- Mechanical model : SUMCOM
- Integrated model exists
- Tuning of the model parameters for individual suspension is necessary
- 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
TF measurements
- Check the mechanical status of the suspension
- Base for the control
- Comparison against the model predictions
Damping control
Hierarchical control
Automatic operation
- Guardian
- Automatic health check
- Status monitor
Desired status before Y-arm lock
- All the sensors diagonalized
- All the actuators diagonalized
- All the TFs reasonably agree with the model
- Damping control satisfies the requirements
Length RMS < ?
Angular RMS < ?
- Hierarchical control is ready
- Maximum actuation range
X um: f < 0.5Hz
YYY nm: 0.5Hz < f < 1Hz
ZZ nm: 1Hz< f < 10Hz
- Response to the feedback input is similar to a single pendulum
- Maximum actuation range
Schedule
- 4/1 - 4/26: ITMY suspension commissioning
- 5/7-5/10: Y-arm lock with feedback to ITMY mass
