This reveals you do not know what you are talking about but can only patch together words to put on a pretense of knowledge. Just like the Chinese boys here.
Anyway, computer assisted/augmented or completely FBW-FLCS flight control surfaces deflections are governed by calculations from these sources:
...
...
The pilot have no control over their calculations. If the J-20 canards are active flight control elements, and signs are likely that they are, then they are constantly in motion. Their deflection angles and rate of deflections are necessary to maintain stable flight in all regimes, from TO-L to supersonic. The only time we can see a flight control surface's visible displacement is at TO-L speed, but when the aircraft is at cruising speed, which is normally several hundreds km/h to just below Mach, large displacements would make aircraft 'depart from controlled flight'.
...
...
At various timestamps such as 1:48 where we can see the F-15's external view, its flight control surfaces' movements are barely noticeable. Then at the end when the jets are landing do we see large deflections of flight control surfaces.
So there is no 'goal to minimize canard movement'. There can be no such goal to accommodate other desires.
