The open loop transfer function of a process is K [{(s + 1) (s + 4)}/{(s + 2) (s + 3)}]. In the root locus diagram, the poles will be at ___________________?
Correct answer: C. -2, -3
- A. -1, -4
- B. 1, 4
- C. -2, -3
- D. 2, 3
Explanation
The poles are the roots of the denominator of the open-loop transfer function, so s = -2 and -3. The numerator roots, -1 and -4, are zeros and do not represent poles.
