What is the overall transfer function for a closed-loop system having a forward-path transfer function of 5/(s + 3) and a negative feedback-path transfer function of 10?

Respuesta :

Answer:

  • transfer function T(S)=[tex]\frac{5}{S+53}[/tex]

Explanation:

NEGATIVE FEEDBACK TRANSFER FUNCTION

negative feedback control of the amplifier is achieved by applying output voltage signal back to inverting input terminal by feedback

transfer function is T=[tex]\frac{g}{1+Gh}[/tex]

where G=forward Path gain

H=negative feedback gain

here G=[tex]\frac{5}{S+3}[/tex]

H=10

T(S)=[tex]\frac{G}{1+GH}[/tex]

=[tex]\frac{5}{S+53}[/tex]
