While looking at the pointing drift over the course of the vent for SR3, Sheila and I noticed a jump in the DAMP_P_INMON channel before vs after the SR3 model restart that was done yesterday (83906) (attachment1). We looked around trying to trace where the discrepancy started until we finally noticed that the 32 coming out of DITHER P was entering DRIVEALIGN as L (attachment2). This was confirmed as the discrepancy when we trended the DRIVEALIGN_L and DRIVEALIGN_P channels and confirmed that before the model restart, DRIVEALIGN_L was (correctly) 0 and DRIVEALIGN_P was (correctly) 32, but after the model restart they had been swapped (bottom middle of attachment1).
Looking at the 2nd and 3rd Simulink model screenshots that Jeff had uploaded in 83911, we see that the ADDFF block takes in LPY in the wrong order - as FF_P_In, FF_Y_In, FF_L_In, and then sends it back out in the wrong order as well - as PITCH_Out, YAW_Out, LONG_Out
.
I've corrected these mistakes (attachment3, attachment4) and recompiled the PR3 and SR3 models, and Erik was available to restart both models for us. Everything looks good now! The discrepencies with DAMP_P_INMON and the Left and Right COILOUTs have been resolved.
