AAGM AAGM

INSTRUCTION NAME: AAGM (analog adaptive gain modifier)

DESCRIPTION: This instruction is used only once per loop and in conjunction with the adaptive

gain PCA. Based on an analog value, it modifies the gain of only the proportional action term of the

PI/PID algorithm. This modifier creates four registers, which are required to store the upper break

point, upper gain factor, lower break point, and lower gain factor. The SVA and SVD inputs remain

unchanged.

When the analog value (operand 1) is below the lower break point (operand 3) or above the upper

break point (operand 4), the analog adaptive gain factor (AAGF) will change linearly, based on the

difference between the analog value and the break point. The lower and upper gain factors

(operands 5 and 6) determine the rate of change in AAGF. Gain factors greater than 1 cause AAGF

to increase as the analog value moves away from the break point, while gain factors less than 1

cause AAGF to decrease. When the analog value is 10 percent away from a break point, AAGF

equals the gain factor.

When the analog value is between the upper and lower break points, AAGF equals 1.
