Subject: simulink just about done. Feedback appreciated. 

So over the whole summer, I've put together, little by little, the simulink model for the path that locks the laser to the reference cavity. I'm going to attach the matlab files in a zip folder. I've tried my best to comment as best as possible and to make the programs as robust as I could possibly think of.

I am also attaching the LISO models to the TTFSS paths and for the fits to the measured PZT and EOM Actuator transfer functions. I'm going to list the links of past elogs that refer that mention these fits. I'm also going to attach the fits themselves.

EOM Actuator Measurement Procedure

PZT and EOM Actuators Fit

A more complete description of my measurements can be found in my surf report

I am still not satisfied with these fits and would like some feedback in improving them. I am most worried about my measured EOM Actuator transfer function fit.
