please have a glance at the file attached.
what I need to do is
To dump that equation in to a processor/micro controller(the variable are the values that are sensed form voltage and current sensors),all those multiplication and division can be done easily. But I cant understand how to create an equation or code for those integration and differentiation terms present there. =( =(
and thanks to both of you, I got some ideas of combining MATLAB with ARDUINO form your comments itself and I am working on it.
