What is the transfer function of positive feedback control system? Assume G(s) to be forward path gain and H(s) to be feedback path gain.
1
\(\frac{{G\left( s \right)}}{{1 - G\left( s \right)H\left( s \right)}}\)
2
\(\frac{{G\left( s \right)}}{{1 - G\left( s \right)}}\)
3
\(\frac{{G\left( s \right)}}{{1 + G\left( s \right)H\left( s \right)}}\)
4
\(\frac{{G\left( s \right)}}{{1 + G\left( s \right)}}\)
