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"..

I've never heard the term "super stall" before so won't try to explain it.
Q (or more properly, q) is an aerodynamicists shorthand for dynamic pressure. On an old fashioned aeroplane with cables and pushrods (known as "reversible controls") you get force feedback that's s function of airspeed. On a modern aircraft with irreversible (FBW or more likely hydraulic controls) you don't get that feedback. So designers incorporate q-feel to give you that differing control force sense with increasing airspeed.
