Pade Delay

Pade approximation of delay block with fixed DelayTime

 

Description

Connections

Parameters

Modelica Standard Library

Description

The Pade Delay component delays the input signal by duration Delay Time.

The delay is approximated by a Pade approximation, that is, by a transfer function

ys=b1sm+b2sm1++bm+1a1sn+a2sn1++an+1us

where the coefficients bk and ak are calculated such that the coefficients of the Taylor expansion of the delay ⅇTs around s=0 are identical up to order n + m. The main advantage of this approach is that the delay is approximated by a linear differential equation system, which is continuous and continuously differentiable.
