The alternative, sliding contact bearings are limited to 2-10 [μm] motion resolution, due to stick-slip motion [[cite:&slocum92_precis_machin_desig]], hence they are not preferred.
|
||||
Stick-slip occurs due to the difference between static and dynamic coefficients of friction in such bearings, which results in an impact-like disturbance in the control system during motion reversal.

#+begin_quote
|
||||
Since the proposal of the first dual-actuation stage composed of a combination of ball screw drives and a rotary motor for the long-stroke stage and piezoelectric actuators for the fine stage in 1988, many studies have been performed.
|
||||
When the coarse actuator and fine actuator are combined, some problems are solved and some other problems develop, such as stability, response speed, and friction.
|
||||
#+end_quote
|
||||
#+begin_quote
|
||||
The motion range of the piezoelectric actuator (short stroke) will at least compensate the motion error of the VCM (long-stroke) and the bandwidth of the piezoelectric actuator is higher than that of the VCM to compensate the system error.

** TODO [#A] Important point of payload mass
|
||||
|
||||
Because the payload's mass can be higher than the mass of the micro-hexapod mass, the coupling becomes very high.
|
||||
|
||||
For most of end-stations, the top stages (for small stroke scans) is quite light, and the sample as well.
|
||||
This way, the short stroke stage dynamics is not coupled to the dynamics of the stages bellow.
|
||||
|
||||
In the NASS case, the payload's mass may be one order of magnitude heavier than the mass of the long stroke top platform.
|
||||
This induce large coupling between stages and is a challenge.

Stacked stages:
|

- errors are combined
|

To have acceptable performances / stability:

- limited number of stages
|

- high performances stages (air bearing etc...)

**** Online Metrology
|

|

The idea of having an external metrology to correct for errors is not new.
|
||||
|
||||
Several strategies:
|
||||
- only used for measurements (post processing)
|
||||
- for calibration
|
||||
- for triggering detectors
|

- for real time positioning control (Figure ref:fig:introduction_active_stations)

- Any application in 6DoF? Maybe new!

Say that high performance systems (lithography machines, etc...) works with calibrated payloads.
|
||||
Being robust to change of payload inertia means large stability margins and therefore less performance.

**** End-Station with Stacked Stages
|
||||
|

Stacked stages:
|
||||
- errors are combined
|

|

To have acceptable performances / stability:
|
||||
- limited number of stages
|
||||
- high performances stages (air bearing etc...)

The idea of having an external metrology to correct for errors is not new.

Several strategies:
|
||||
- only used for measurements (post processing)
|

- for calibration
|

- for triggering detectors
|

- for real time positioning control (Figure ref:fig:introduction_active_stations)

**** Long Stroke - Short Stroke architecture
|

|

Speak about two stage control?
|

- Long stroke + short stroke
|

- Usually applied to 1dof, 3dof (show some examples: disk drive, wafer scanner)
|
||||
- Any application in 6DoF? Maybe new!
|
||||
- In the table, say which ones are long stroke / short stroke. Some new stages are just long stroke (voice coil)
