Summary

[edit]
Description
English: A typical transient response for an under-damped second order system showing the system characteristics. the damping factor is 0.5. The terms represented are:
  1. = peak time (time required to reach the first peak)
  2. = delay time (time to reach 50% of final value for the first time)
  3. = rise time (time to rise from 0 to 100% value)
  4. = maximum overshoot

Created in maxima:

beta(zeta) := sqrt(1-zeta^2);
theta(zeta) := atan(beta(zeta)/zeta);
h_under(wt) := 1 - beta(0.5)^-1*exp(-0.5*wt)*sin(wt*beta(.5)+theta(0.5));
