Let's say the inputs you pass are Response and Time, and the outputs you require are damping ratio (Zeta), natural frequency (Wn), damped frequency (Wd) and transfer function (h) The following is a big picture of what you would be doing:
WebMar 5, 2024 · The damping ratio, \(\zeta\), is a dimensionless quantity that characterizes the decay of the oscillations in the system’s natural response. The damping ratio is bounded as: \(0<\zeta <1\). As \(\zeta \to 0\), the complex poles are located close to the imaginary axis at: \(s\cong \pm j{\omega }_n\). The resulting impulse response displays ... WebMar 5, 2024 · The damping ratio constraint requires that: θ ≤ ± cos − 1ζ, where θ is the angle of the desired root location from the origin of the complex plane. The rising time constraint places a bound on the natural frequency of the closed-loop roots as ωn ≥ 2 tr. These constraints are summarized below: σ ≥ 4.5 ts, ωn ≥ 2 tr, θ ≤ cos − 1ζ Example 4.2.2
