Don't know if this is what you are seeking, but i'll give it a try anyway..
Q- Feel (Artificial feel), used when hydraulic actuators (irreversible servo system) operates the controls..
When hydraulic pressure moves the control surfaces any "control feel" is removed from the pilot (Stick force).
To prevent this, artificial feel units are fitted to these systems which are designed to give pilot control feel which is proportional to the speed of the aircraft and to the amount of control surface movement made..
These artificial feel units may vary from a simple spring box to a Q- pot system which make use of the pitot pressure..
And Super- stall, hmm, i think another word for it is "Deep- stall"..
