DaveS: Try it now. The PID code is running now, but the code that actually gimbals the engines is still disabled.

OK, no freeze, so I guess that exhonorates the PID controller code.

That leaves the part which turns the gimbal actuator commands into engine orientation.
 
That's interesting. All the code I commented out earlier is now working again, and it doesn't seem to be causing freezes.
 
Mine is !! It freezes just before tower clear.

What about using assertions finally, instead of just assuming that the PID output will not cause the NormZ function to throw a invalid vector into the Orbiter functions.

Integrative and derivative parts have both good reasons to cause the controller outputs to become large, once the frame rates are far enough away from normal frame rates used for testing.
 
I've added error logging to the NormZ function.
Donamy: I've sent you the new dlls. After you run a launch scenario, see if there are any error messages in the log.


-----Post Added-----


Figured out what the bug was (I think). When the roll starts, the target rate goes from 0 to 12 deg/sec, which would cause a spike in the derivative term from the PID controller. On my computer, the framerates must be low enough to smooth this own to acceptable values; higher framerates would be causing problems.
 
I don't see any errors in the orbit log
 
See if the latest version stops the freezing. It fixes the problem mentioned above, although there seems to be something else going on here.
 
The freezing has stopped however, there are more issues.

1. There is still a slight wabble during the roll program. At t-2 sec the SSMEs get real close together and act as one, with the the SRB gimbaling also. Is this simulated?

2. I can't have the STBD MPMs stowed on the pad and the payload is shifted forward in the bay quite abit when on the pad. It is in the correct position on orbit.

3. When I'm in the center aft flightdeck position and I flip the STBS latch release, I loose the payloadbay, it returns if I press X to zoom out, then disappears again when I press Z to zoom in.

4. I can't move the RMS once grappled again, is there a way to release the payload from the bay ?

I'll look at the roll program wobble and the other bugs. At the moment, gimballing before liftoff is not simulated. Also, can you post a screenshot of #3? I'm not quite sure what you mean here.

Can everyone else confirm that the freezing has disappeared?

I haven't been able to reproduce the payload shifting. Which scenario are you using?
 
I've found out that it is only attachment 5 that is shifted, so I think you ignore this one. DaveS doesn't have it.

Any luck on the OBSS MPMs bug ?

And speaking of that, it seems that the STO/DPY talkback for the OBSS isn't working. It's stuck in DPY.
 
Donamy: The OBSS bug should be fixed now. I've changed the scenario file entries a bit, though. The 'STBD_MPM' entry is used to add the OBSS MPMs to the shuttle, and the 'STBD_MPM_ROLLOUT' entry is used to set the MPMs to the deployed or stowed state.
 
I have this at the end of the Discovery in the 119 Launch scenario, and the STBD MPMs are deployed and won't retract.

Code: 
  MPM
  STBD_MPM_ROLLOUT 0 0.0000
  STBD_MPM_LATCHES 0 0.0000
  RMS
  ARM_STATUS 0.500537 0.012731 0.014874 
0.505084 0.507947 0.504748
  RMS_ELBOW_CAM 0.0000 0.0000
  RMS_ROLLOUT 0 0.0000
  RMS_LATCHES 0 0.0000
END

Are these new .dlls or the ones you sent me a few days ago ?
