.ModelicaAdditions.Blocks.Continuous.CritDamping

Information

This block defines the transfer function between the input u=inPort.signal[1] and the output y=outPort.signal[1] as an n-th order filter with critical damping characteristics and cut-off frequency f=1/T. It is implemented as a series of first order filters.

If transients at the simulation start shall be avoided the states x need to be initialized with the start value of the input.

     y = ------------- * u
