blockFirstOrder_variableDamping
First order transfer function block (= 1 pole) with variable damping
Extends from Modelica.Blocks.Interfaces.MISO (Multiple Input Single Output continuous control block).
Information
1. Purpose of model
This blocks defines the transfer function between the input u and the output y (element-wise) as first order system with variable damping:
k
y = ------------ * u
T * s + 1
