F-86F Sabre Rocks Side to Side between waypoints on autopilo

Designing a stable autopilot is one of the hardest things. Need help?

A: Are you positive it is now using your custom autopilot file?

B: can you paste the PID here inside a [code]
Waste of time. Goodbye forever.

Im sure im using the custom autopilot , unless I have done the code wrong.

Here is the autopilot code:

You are only changing the wing leveller now right?

Try a TI of 10 and s Kp of 0.005. Test wing leveller only.

Yes, I have been only changing the kp value of the wing leveler. I'll try what you mentioned today and see what happens.

That fix did not do anything to help the problem. I can proceed on with shrinking the kp while keeping that ti value.

Hmm. I feel that either this plane is EXTREMELY SENSITIVE, or there is something else wrong.

Could you upload your aircraft.zip anywhere? I'd like to look at the FDM.

I guess you could also set the debug to "true" on that controller. If it really is that controller that is running, you'll get masses of output in your console. If there's no output, it's not using that controller when you expect.

OK, I noticed something:


Turnit wrote:Here is the code where I entered the location of the autopilot into the -set file:

<path>Aircraft/F-86/Systems/autopilot.xml</path>
</autopilot>


That needs to be inside <systems> </systems> and inside <sim> </sim>in the set file.

Example

<sim>

Random stuff like name, description, rating, other stuff etc.

<systems>
<autopilot>
<path>Aircraft/F-86/Systems/autopilot.xml</path>
</autopilot>
</systems>

</sim>

    <text>---Take Off---
Flaps down 10 degrees, Apply full power. Beware, the Engine takes long time to spool up. Lift Nosegear at 120-130 knots Lift off at about 150 knots.  A high AOA during takeoff is normal. Leading edge slats extend and retract automatically.

---Landing---
Start Approach by opening speedbrakes and slow down. Flaps and Gear can be lowered below 185 kts. Downwind should be at about 170 kts. To ensure enough power for a go around maintain at least 60-70% RPM. Reduce speed further to 135 kts at final. Cut Power when landing is ensured. Don't try a full stall landing because the AOA would be so high that the aft fuselage section would drag.

Hmm, that's correct. It should work....

Can I see the aircraft in a zip somewhere?

OK I find some time to mess around
I find in the wing leveller a Kp of 0.35 works OK

This FDM is VERY weird. Roll is slowish, and unstable, pitch is really jerky, thrust is no very effective in either increasing or deceasing power.

I suggest fixing the FDM, before trying to tune an AP. The HDG mode seems to work fine.
