frfit
frequency response fit
Calling Sequence
sys=frfit(w,fresp,order) [num,den]=frfit(w,fresp,order) sys=frfit(w,fresp,order,weight) [num,den]=frfit(w,fresp,order,weight)
Arguments
- w
positive real vector of frequencies (Hz)
- fresp
complex vector of frequency responses (same size as
w
)- order
integer (required order, degree of
den
)- weight
positive real vector (default value
ones(w)
).- num,den
stable polynomials
Description
sys=frfit(w,fresp,order,weight)
returns a bi-stable transfer function
G(s)=sys=num/den
, of of given order
such that
its frequency response G(w(i))
matches fresp(i)
, i.e.
freq(num,den,%i*w)
should be close to fresp
.
weight(i)
is the weight given to w(i)
.
