Formulas used in the experiment
- Characteristic equation is given by : s2 + 2ζωns + ωn2=0
- Natural frequency : ωn = √(coefficient of constant term)
- Damping ratio : ζ = (coefficient of s1)/2wn
- Settling time : ts = 4/ζ*ωn
- Peak time : tp = π/ωn* √(1-ζ2)
- Rise time : tr = π-Φ/ωn* √(1-ζ2) where Φ = tan-1√((1-ζ2)/ζ)
- Delay time : td = (1+(.7*ζ))/ωn
- Maximum overshoot : Mpe-(ζ*π)/(√(1-ζ2))
