Discrete Transfer Function

Discrete Transfer Function block

 Description The Discrete Transfer Function (or Transfer Function) component defines the transfer function between the input signal $u$ and the output signal $y$. $\frac{y\left(z\right)}{u\left(z\right)}=\frac{{b}_{1}{z}^{{n}_{b}-1}+{b}_{2}{z}^{{n}_{b}-2}+\cdots +{b}_{{n}_{b}}}{{a}_{1}{z}^{{n}_{a}-1}+{a}_{2}{z}^{{n}_{a}-2}+\cdots +{a}_{{n}_{a}}}$ State variables, $x$, are defined according to controller canonical form. Initial values of the states can be set as start values of $x$.
