The quad matlab model generate_QUAD_Model_Production.m script has 3 new features:

1) reading in live damping filters

2) reading customized parameter files for the suspensions

3) building models with fiber violin modes based on the measured frequencies and Qs

svn up the following directory:  ../SusSVN/sus/trunk/QUAD/Common/MatlabTools/QuadModel_Production/

Here is an example of how to build a model with all 3 features:

quadModel = generate_QUAD_Model_Production(frequency_vector,'h1etmy',[],0,true,'liveh1etmy',0,0,true,8);

* frequency_vector is some frequency vector you specify.

* 'h1etmy' is the customized H1 ETMY parameter file (quadopt_fiber is the general quad file). All other quads have parameter files now too, but h1etmy is the only unique one at this point.

* true (the first one) says you want damping

* 'liveh1etmy' says you want live filters from H1 ETMY. The 'live' prefix is what triggers the flag to read live filters. The code imports the filters from 5 minutes in the past, to allow for some latency.

* true (the second one) says you want violin modes

* 8 says you want the first 8 violin modes in the model (2 is the default if not specified)

The h1etmy.m parameter file includes the measured mode frequencies for the first 8 violin modes at the bottom of the file. More can be added as desired. There is also a place holder for the measured Qs, but I am not aware of any measured values. The violin mode script (called by the generate script) will incorporate any measured values found in the parameter file. It will use modeled values for those that are not specified.

I'll leave the testing of the live filter reading to the people at the sites, since this is harder to do off site. Please let me know if something doesn't work properly. I've only gone as far as checking that it compiles (on my laptop) and that the closed loop system is stable.

The generate script has instructions for setting up your computer to run the live filters. This text is copied here:

Checkout the following addpath paths:

svnDir = '../NbSVN/aligonoisebudget/trunk/'   (the '..' must be the same as for the SusSVN, e.g. /ligo/svncommon/)    

addpath(genpath([svnDir 'Externals/SimulinkNb/']))
