Hysteresis

Hi,

A33Zab

PF applied large stimuli to the plane.

I agree with PJ2, just sit and wait (30 sec.) is proven to be the best strategy in case of UAS.


We may say this "technique" is an "hysteresis like" one. No reaction (in the loop) until a given threshold. In absence of other solution I AGREE this is WISE.

Even better would be no UAS at all. It probably is achievable.


As a researcher i have to remove the "probably" in the phrase.

And i am not not focusing on the probes. I look to the System.

The whole "processing" of the probes data IMO should be reviewed.

As i understand the a/c operation degrades EXACTLY when you need most.

Who knows what PF saw in the transitory, just after AP quit?

But this is to be covered in another post i am preparing:

Transient in Feedback Systems (II)
