getLFTModel
Decompose generalized LTI model
Syntax
[H,B,S] = getLFTModel(M)
Description
[H,B,S] = getLFTModel(M)H, B, and S that
make up the Generalized matrix or Generalized
LTI model M. The model M decomposes
into H, B, and S.
These components are related to M as shown in
the following illustration.
The cell array B contains the Control
Design Blocks of M. The component H is
a numeric matrix, ss model, or frd model
that describes the fixed portion of M and the
interconnections between the blocks of B. The
matrix S = blkdiag(S1,...,Sk) contains
numerical offsets that ensure that the interconnection is well-defined
when the current (nominal) value of M is finite.
You can recombine H, B,
and S into M using lft, as follows:
M = lft(H,blkdiag(B{:})-S);Output Arguments

getLFTModelgives you access to the internal representation of Generalized LTI models and Generalized Matrices. For more information about this representation, see Internal Structure of Generalized Models.
