Second-Order Systems: Damping Ratio, Natural Frequency, Overshoot, Peak & Settling Time
This lesson is part of the course
In this lesson
You compute the natural frequency and damping ratio of a toy spring-mounted arm, tabulate its step response with the exact second-order formula, find the overshoot and build a table of overshoot over ζ.
