Line 1: Line 1:
The closed loop transfer function <math>G(s)\,</math> (which means <math>H_{yr}(s)\,</math>) should be <math>\frac{\omega_0^2}{s^2+2\zeta\omega_0s+\omega_0^2}\,</math>. The last term of the denominator is <math>\omega_0^2\,</math> rather than <math>\omega_0\,</math>, and the second term is missing an additional <math>s\,</math>.
For <math>\zeta<1\,</math>, the corresponding equation should be:
 
<math>y(t)=k\Big(1-e^{-\zeta\omega_0t}\cos{\omega_dt}-\frac{\zeta}{\sqrt{1-\zeta^2}}e^{-\zeta\omega_0t}\sin{\omega_dt}\Big)</math>.
