Subject: SUS Plant Plan for New Optics 

[Ian, Tega, Raj]

This is the rough plan for the testing of the new suspension models with the created plant model. We will test the suspensions on the plant model before we implement them into the full

  • Get State-space matrices from the surf model for the SOS. Set up simplant model on teststand
    • The state-space model is only 3 degrees of freedom. (even the surf's model)
    • There are filter modules that have the 6 degrees of freedom for the suspensions. We will use these instead. I have implemented them in the same suspension model that would hold the state space model. If we ever get the state space matrices then we can easily substitute them.
  • Load new controller model onto test stand. This new controller will be a copy of an existing suspension controller.
  • Hook up controller to simplant.  These should form a closed loop where the outputs from the controller go into the plant inputs and the plant outputs go to the controller inputs.
  • Do tests on set up.
    • Look at the step response for each degree of freedom. Then compare them to the results from an existing optic. 
      • Also, working with Raj let him do the same model in python then compare the two.
  • Make sure that the data is being written to the local frame handler.
