Compare A to B via a mixer and put in a PID loop.
Compare A to C via a mixer and put in a PID loop.
Sum A with B with C via a three input analog adder.
A to B via PID
A to C via PID
A to D via PID ….
… sum A with B with C with …. M via a 13 input analog adder.
There are several other ways to do it.
