Damping Ratio & Natural Frequency

Inside this lesson

Express the second-order characteristic equation in standard form using ζ and ω0
Convert between the α-notation from earlier lessons and the ζ-notation used in control engineering
Classify a system's damping regime (overdamped, critically damped, underdamped, undamped) using ζ alone
Compute ζ and ω0 for a series RLC circuit from R, L, and C values
Explain why ζ is a universal parameter that appears across electrical, mechanical, and control systems
