blockCriticalDamping
Output the input signal filtered with an n-th order filter with critical damping
Extends from Modelica.Blocks.Interfaces.SISO (Single Input Single Output continuous control block).
Information
This block defines the transfer function between the input u and the output y as an n-th order filter with critical damping characteristics and cut-off frequency f. It is a slightly simplified version of the "Modelica.Blocks.Continuous.CriticalDamping" block from the MSL 3.2.1. It doesn't provide the same initialization capabilities as the MSL block, since the initialization of clocked partitions is currently performed different to the continuous time partitions.
Parameters

|---|---|---|---|
| Integer | n | 2 | Order of filter |
| Modelica.SIunits.Frequency | f | Cut-off frequency | |
| Boolean | normalized | true | = true, if amplitude at f_cut is 3 dB, otherwise unmodified filter |
