We wish here to see if we can determine an optimal stiffness of the nano-hexapod such that: - Section [[sec:spindle_rotation_speed]]: the change of its dynamics due to the spindle rotation speed is acceptable - Section [[sec:micro_station_compliance]]: the support compliance dynamics is not much present in the nano-hexapod dynamics - Section [[sec:payload_impedance]]: the change of payload impedance has acceptable effect on the plant dynamics * Spindle Rotation Speed <> ** Introduction :ignore: ** Matlab Init :noexport:ignore: #+begin_src matlab :tangle no :exports none :results silent :noweb yes :var current_dir=(file-name-directory buffer-file-name) <> #+end_src #+begin_src matlab :exports none :results silent :noweb yes <> #+end_src #+begin_src matlab :tangle no simulinkproject('../'); #+end_src #+begin_src matlab open('nass_model.slx') #+end_src ** Conclusion :ignore: * Micro-Station Compliance Effect <> ** Introduction :ignore: - take the 6dof compliance of the micro-station - simple model + uncertainty ** Matlab Init :noexport:ignore: #+begin_src matlab :tangle no :exports none :results silent :noweb yes :var current_dir=(file-name-directory buffer-file-name) <> #+end_src #+begin_src matlab :exports none :results silent :noweb yes <> #+end_src #+begin_src matlab :tangle no simulinkproject('../'); #+end_src #+begin_src matlab open('nass_model.slx') #+end_src ** Conclusion :ignore: * Payload "Impedance" Effect <> ** Introduction :ignore: ** Matlab Init :noexport:ignore: #+begin_src matlab :tangle no :exports none :results silent :noweb yes :var current_dir=(file-name-directory buffer-file-name) <> #+end_src #+begin_src matlab :exports none :results silent :noweb yes <> #+end_src #+begin_src matlab :tangle no simulinkproject('../'); #+end_src #+begin_src matlab open('nass_model.slx') #+end_src ** Conclusion :ignore:
