The Second Order component defines a second-order transfer function system.

$\frac{y\left(s\right)}{u\left(s\right)}\=\frac{k}{{\left(\frac{s}{w}\right)}^2\+2\mathrm{D}\left(\frac{s}{w}\right)\+1}$

The Signal Size parameter allows the block to operate on a vector of signals rather than a single signal.

$\stackrel{\.}{y}\=y_d$

$\stackrel{\.}{y_d}\=w\left(w\left(ku-y\right)-2\mathrm{D}{y}_d\right)$
