- control.frd(d, w)¶
Construct a frequency response data model
frd models store the (measured) frequency response of a system.
This function can be called in different ways:
Create an frd model with the given response data, in the form of complex response vector, at matching frequency freqs [in rad/s]
Convert an LTI system into an frd model with data at frequencies freqs.
sys – New frequency response system
- Return type
>>> # Create from measurements >>> response = [1.0, 1.0, 0.5] >>> freqs = [1, 10, 100] >>> F = ct.frd(response, freqs)
>>> G = ct.tf(, [1, 1]) >>> freqs = [1, 10, 100] >>> F = ct.frd(G, freqs)
