Question

그림과 같은 블록선도(순방향 $G(s)$, 두 부귀환 $H_{1}(s)$·$H_{2}(s)$)의 전달함수 $\dfrac{C(s)}{R(s)}$ 는?

Accepted Answer

$\dfrac{G(s)}{1+G(s)(H_{1}(s)+H_{2}(s))}$

Answer

$\dfrac{G(s)H_{1}(s)H_{2}(s)}{1+G(s)H_{1}(s)H_{2}(s)}$

Answer

$\dfrac{G(s)}{1+G(s)H_{1}(s)H_{2}(s)}$

Answer

$\dfrac{G(s)}{1-G(s)(H_{1}(s)+H_{2}(s))}$
