Simulink Control Design™ - MathWorks

(Tuis.) #1

  • If you configured s.Parameters and specified s.OperatingPoints as a single
    operating point, the software computes a linearization for each parameter grid point.
    The software uses the specified operating point as the linearization operating point.
    linsys is returned as a state-space model array of the same size as the parameter
    grid.

  • If you configured s.Parameters and specified s.OperatingPoints as multiple
    operating point objects, the software computes a linearization for each parameter grid
    point. The software requires that s.OperatingPoints is the same size as the
    parameter grid specified by s.Parameters. The software computes each linearization
    using corresponding operating points and parameter grid points. linsys is returned
    as a state-space model array of the same size as the parameter grid.

  • If you configured s.Parameters and specified s.OperatingPoints as multiple
    simulation snapshot times, the software simulates and linearizes the model for each
    snapshot time and parameter grid point combination. Suppose that you specify a
    parameter grid of size p and N snapshot times. linsys is returned as a state-space
    model array of size N-by-p.


info — Linearization information
structure

Linearization information, returned as a structure with the following fields:

Offsets — Linearization offsets
[] (default) | structure | structure array

Linearization offsets, returned as [] if s.Options.StoreOffsets is false. Otherwise,
Offsets is returned as one of the following:


  • If linsys is a single state-space model, then Offsets is a structure.

  • If linsys is an array of state-space models, then Offsets is a structure array with
    the same dimensions as linsys.


Each offset structure has the following fields:

Field Description
x State offsets used for linearization, returned as a column vector of length nx,
where nx is the number of states in linsys.
y Output offsets used for linearization, returned as a column vector of length
ny, where ny is the number of outputs in linsys.
