Solved Example: 9333-02
Roots on the imaginary axis makes the system:
A. Stable
B. Unstable
C. Marginally stable
D. Linear
Correct Answer: C
Damping
Damping in control systems refers to the suppression or reduction of oscillations, vibrations, or overshoot in a dynamic system. It is essential for improving system stability and response. Damping is critical to prevent undesirable and excessive oscillations that can lead to instability, reduced control system performance, and potential damage in industrial processes.
