-#+begin_quote
-Kinematics of the DCM is described (both for motors and sensors). Transformations matrices are derived and all notations and conventions are well defined.
-#+end_quote

-[[file:dcm-metrology/index.html][Metrology]]
-#+begin_quote
-Internal metrology of the DCM (i.e. interferometers) is described. Methods to properly initialize and calibrate the metrology are proposed.

-[[file:dcm-feedback-control/index.html][Feedback Control]]
-#+begin_quote
-This project deals with the Feedback Control of the DCM:
-
-Identification of the system's dynamics Change of coordinates Feedback controller design Obtained performances in closed loop
-#+end_quote
-
-[[file:dcm-user-guide/index.html][User Guide]]
-#+begin_quote
-The goal of this repository is to provide a simple guide for the use of the DCM.

-#+begin_quote
-This repository includes all the work done in order to calibrate the errors induced by the stepper motors.

-#+begin_quote
-This project summarized all the work done on the Laser Setup. This includes alignement, calibration, noise and stability measurements.

-#+begin_quote
-The control of the Bragg angle using the Aerotech controller is described (control architecture, identified dynamics, etc.).

-[[file:dcm-simscape/index.html][Multi-Body model (Simscape)]]
-#+begin_quote
-Multi-body model of the DCM using Simscape (Matlab Toolbox). Dynamics of the system is studied, matched with the identified dynamics. Feedback control is applied, and the model is used to study possible improvements.
