Question

Consider a feedback control system with loop transfer function
$G\left(s\right)H\left(s\right)=\frac{K(1+0.5s)}{s(1+s)(1+2s)}$
The type of the closed loop system is

• A. zero
• B. one
• C. two
• D. three

Answer 1

The correct option is B one

Number of poles at origin of open loop transfer function gives the type of the system.
