** TODO [#C] Noise budgeting to have specifications
|
||||||
|
|
||||||
|
Simplified model (uniaxial?)
|
||||||
|
From maximum induced vibration, and estimated bandwidth (S and T), estimate the maximum:
|
||||||
|
- Actuator noise (i.e DAC + voltage amplifier)
|
||||||
|
- force sensor noise (i.e. ADC) + encoder noise?
|
||||||
|
- external metrology noise? (not very relevant, maybe this should be assumed, similar to Attocube noise [[file:~/Cloud/work-projects/ID31-NASS/matlab/test-bench-attocube/test-bench-attocube.org][test-bench-attocube]])
|
||||||
|
|
||||||
|
=> *Specifications*
|
||||||
|
|
||||||
|
And specifications in terms of bandwidth, voltage ranges, etc...
|
||||||
|
|
||||||
|
** TODO [#C] Find instrumentation that meet such specification
|
||||||
|
|
||||||

How to read force sensor, etc...

Sources:
|
||||||
|
- ADC: measured
|
||||||
|
- PD200: measured
|
||||||
|
- Encoder: measured
|
||||||
|
- ADC (force sensors): measured
|
||||||
|
- Ground motion: estimated
|
||||||
|
|
||||||
|
By taking into account all those sources, we should be able to do a noise budgeting and compare with the obtain measurements.
|
||||||
|
|
||||||
|
We need the following transfer functions:
|
||||||
|
- from ground motion (x,y,z) to strut motion (1 to 6) => Simscape
|
||||||
|
- from DAC voltage to strut motion => identified FRF
|
||||||
|
- from PD200 voltage to strut motion => identified FRF
|
||||||
|
- from ADC noise to strut motion => identified FRF + Controller (closed-loop)

The goal is to show that each element in the system has been properly chosen based on certain requirements.
|

|
|
||||||
|
In order to determine the maximum noise of each instrumentation, a dynamic error budgeting is performed in Section ref:sec:instrumentation_dynamic_error_budgeting.
|
||||||
|
|
||||||
|
The required instrumentation are then selected based on obtained noise specifications and other requirements summarized in Section ref:sec:instrumentation_choice.
|
||||||
|
|
||||||
|
The received instrumentation are characterized in Section ref:sec:instrumentation_characterization.

|
Need the multi-body model with controllers
|

|
- Suppose a maximum error ASD.
|

|
Suppose flat ASD, bandwidth of ~200Hz, maximum RMS of ~10nmRMS => x nm/sqrt(Hz)
|
