PT2-Term (able to oscillate)

This function block realizes a second-order lag proportional transitions term that is able to oscillate.

The output oscillates if the attenuation is in the range of 0 < A < 1.

Operations

The PT2-term realizes the following function:

Step response (variable attenuation, A:D, TC:T):

Step response (variable time constant, A:D, TC:T):

Signals

Name I/O Type(s) Function
X I FLOAT Input signal
TC I FLOAT Time constant in [s]
A I FLOAT Attenuation
Y O FLOAT Output signal

Comments

This function block is typically used for simulation of dynamic processes.
