For a feed back control system to be stable, the _________________?
Correct answer: B. Poles of the closed loop transfer function should lie in the left half of the complex plane
- A. Roots of the characteristic equation should be real
- B. Poles of the closed loop transfer function should lie in the left half of the complex plane
- C. Bode plots of the corresponding open loop transfer function should monotonically decrease
- D. Poles of the closed loop transfer function should lie in the right half of the complex plane
Explanation
A continuous-time linear feedback system is stable when all closed-loop poles lie in the left half of the s-plane. Right-half-plane poles cause growing responses, while poles need not all be real.
