Therefore, when evaluated at the linearization of the block is zero. The source of
the input is the first output of the second-order integrator, which is dependent upon the
state theta. Therefore, this block will linearize to zero if , where is an
integer. The same condition applies for the other Trigonometric Function in the
angle_wrap subsystem.
If these blocks are not expected to linearize to zero, you can modify the operating point
state theta, and relinearize the model.
Run Prebuilt Advisor Queries
The Linearization Advisor provides a set of prebuilt queries for filtering block diagnostics.
For example, the Linearization Advice query is the default query run when the advisor
is first created and includes blocks on the path that:
- Have diagnostic messages regarding the block linearization.
- Linearized to zero.
- Have substituted linearizations.
To run a different prebuilt query, on the Advisor tab, in the Queries gallery, click the
query. For example, click Zero I/O Pair on Path.
