Information

Description

Partial interface for a discretised continuous time block.
Each block has a single input anda single output (SISO).

Discretisation

For each block is defined a sampling time Ts and a coefficient alpha.
The discretisation of the continuos time transfer function has been performed with the bilinear transformation formula

                 z - 1 
  s = ------------------------------
        z*alpha*Ts - (alpha - 1)*Ts

that is equivalent to

Forward Euler (FE) if
```
alpha = 0
```
Backward Euler (BE) if
```
alpha = 1
```
Tustin (TU) if
```
alpha = 0.5
```
