Once the analytical formula of a discrete transfer function is obtained, it is possible to vary some parameters in real time. Once the analytical formula of a discrete transfer function is obtained, it is possible to vary some parameters in real time.
This is easily done in Simulink (see Figure [1](#figure--fig:variable-controller-simulink)) where a `Discrete Varying Transfer Function` block is used.

The coefficients are simply computed with a Matlab function. The coefficients are simply computed with a Matlab function.
