Question 1
For a second-order control system, if the damping ratio $\zeta$ is exactly $1$, the system is described as:
  • Underdamped
  • Overdamped
  • Critically damped✔️
  • Undamped
Correct Answer Explanation
A damping ratio $\zeta = 1$ indicates a critically damped system, which returns to equilibrium in the shortest time without oscillation.
