Question

An open loop system represented by the transfer function is

$G\left(s\right)=\frac{(s-1)}{(s+2)(s+3)}$

• A. stable and of the minimum phase type
• B. stable and of the non-minimum phase type
• C. unstable and of the minimum phase type
• D. unstable and of the non-minimum phase type

Answer 1

The correct option is B stable and of the non-minimum phase type

$1+\frac{s-1}{(s+2)(s+3)}=0$

$s^2+6s+5=0$



There is no root in RHS of s-plane.
