블록 선도에서 $r(t) = 25, \quad G_1=1, \quad H_1=5, \quad c(t)=50$ 일 때 $H_2$ 를 구하면?

Subscribe to see the correct answer.

$\dfrac{-2}{5}$

$\dfrac{-2}{3}$

$\dfrac{-1}{4}$

$\dfrac{-1}{10}$

Solution

$\dfrac{C}{R} = \dfrac{G}{1+GH}$

$\dfrac{50}{25}= \dfrac{1}{1+1\times 5 \times H_2 }$

$H_2 = -\dfrac{1}{10}$

Correct answer 4
