The approach requires transfer function of system and analysis in frequency domain with BODE analysis or Root Locus. Then gains can be computed and entered. If system is dynamic changing load, then a smart sweep in startup and step function test can be used to optimize stability on startup. But temperature rise in magnetics or variation of magnet strength may alter gain of PID loop for example, so this requires compensation.
Not necessarily.
By monitoring the response of the system, you can determine whether there is acceptable overshoot/response time, etc. Then you can tune the system using any number of methodologies, for example: Good Gain, Zeigler-Nichols, Cohen-Coon or, my favorite, experience. You don't HAVE to know the system transfer function, and in many cases it's impossible to know.
