i would like to start for thanking for taking the time to read this

little discussion of mine!

my aim is to produce a battery emulator, and not just any battery

emulator but a zinc-air battery emulator. what i basically have to do

is get a mathematical model of a battery and implement it in hardware:

a power source, a microcontroler, some D/A and A/D converters some

temeperature sensors (which i might actually drop) and voila my

battery emulator .

in order to acheive this i have undertaken some EIS analysis of the

batteries and am pretty close to getting an equivalent circuit that

fits very nicely with the measured data. i plan from this equivalent

circuit to obtain a transfer function for my system in the s domain.

now here comes the question! what i need your guys input for is to

figure out how i can make a feedback for my system. it is not enough

to just have a transfer function because without a feedback the output

will stay constant...diferent from input naturally but constant over

time. this feed back however has to be sensitive about the load of the

system and in this way reduce the input voltage so that the output

voltage gets modeled in the way a battery would modulate its output

voltage dependant on the load. i have no idea where i should start to

think about how my feedback system should look like.

this seems very difficult to me and i need some suggestions about how

i can tackel the problem!!

any idea will be greatly appreciated!

THANK YOU SOOO MUCH FOR YOUR TIME!!
