Origin of equation of current limiting

[hyonlim]

Hi.
I've been working around current limiting and RPM feed forward controller implemented in ESC32.
However, it is hard to tell the origin (reference paper, or theory) of CL1~5TERM.
Actually, no comments on this equation even ground and onboard code.

Can anyone point out some reference document of this code?

maxVolts = p[CL1TERM] + p[CL2TERM]*rpm + p[CL3TERM]*p[MAX_CURRENT] + p[CL4TERM]*rpm*maxCurrentSQRT + p[CL5TERM]*maxCurrentSQRT;

There are none. The equation was discovered through a brute force search by adaptive algorithms of my design. It does a very good job of describing the relationship between voltage, RPM & current with very few terms. But there's no proof for it.
