saturation and the result
#1
Lately I have had the error "saturation" it might be due to removing the IMU from the hat and placing it away from the Tinypilot computer.
This helps tremendously with reducing interference from other electronics.
The cable is just over 1m in length, I will try to add an extender to solve it.

But what I am most concerned with is the result of "saturation" it turns the rudder hard to port. Is there anyway to stop this from happening when saturation is reached? It can be very dangerous.

saturation has nothing to do with the magnetic sensors
It is a small hint indicating that you could probably use a stronger/faster motor.

It should not turn the rudder hard to port, can you reproduce this? It should not actually be dangerous if the autopilot does doesn't unexpected, only inconvenient let us hope.

Thanks Sean, I can reproduce this, it seems to be related to the DD setting. 

What is happening is the Autopilot is doing fine keeping a heading and then the DD turns blue, then the motor instead of making small adjustments, turns hard in the opposite direction it should be (I think "to port" was a coincidence). I watched the gains all day today, and it is reduced if if I reduce the DD value to .1 instead of .17 but it still happens frequent enough to be concerned especially when I am at speed and hit a wave, the DD will turn blue almost every time. 
Here is a poor video of a tame event. You can hear the hydraulic motor power up for a few seconds when DD turns blue.
Thoughts?

does it turn in the opposite direction both ways?

are you sure it's turning the wrong way?

What if you just make DD zero?

Thanks Sean
I will do more testing to confirm the direction and also try DD with zero

Hi rastam4n,

I am having a somewhat similar problem and I am wondering if you have any more info about this?

Thanks,

Colm.
