12.6.10

Finally managed to get all 3 control situations running on the same disturbance data. For some reason, the bias WF changes significantly from time to time, forcing me to do a realignment each time. The usual symptom of this is a crappy poke matrix, or highly saturated commands when identifying the CL dist. model.

Anyway, something's screwed up with the adaptive loop (AO) as shown below. In the past (and I think in theory), it has outperformed the LTI loop since it can better compensate for plant modeling error. One possibility is that the adaptive filter order is insufficient (right now, the adaptive filter is FIR with order 4). I think I'm going to update the code I have to compute the optimal FIR filter so I can look at how the theoretical FIR impulse looks.




For tomorrow:
- Update FIR code
- Figure out what the deal is with the target camera so I can get some Strehl ratio measurements.
