Field Description
u Input offsets used for linearization, returned as an nu-by-1-by-N 1 -by-...-by-
Nm array, where nu is the number of inputs in the linearized system.
dx Derivative offsets for continuous time systems, or updated state values for
discrete-time systems, returned as an nx-by-1-by-N 1 -by-...-by-Nm array.For instance, suppose that your model has three inputs, two outputs, and four states. If
you linearize your model using a 5-by-6 array of operating points, offsets contains
arrays with the following dimensions:
- offsets.x — 4-by-1-by-5-by-6
- offsets.y — 2-by-1-by-5-by-6
- offsets.u — 3-by-1-by-5-by-6
- offsets.dx — 4-by-1-by-5-by-6
To configure an LPV System block, you can use the fields of offsets directly. For an
example, see “Approximating Nonlinear Behavior Using an Array of LTI Systems” on page
3-103.
