You can diagnose potential linearization issues using this information.Diagnostic Messages
Linearization diagnostic messages indicate blocks with properties or linearizations that
correspond to common linearization problems. Fixing linearization issues identified in
diagnostic messages is a good first step when troubleshooting your linearization.Some block configurations that can generate diagnostic messages include:- Blocks with nondouble input or output signals and no predefined exact linearization.
Such blocks linearize to zero and generate diagnostic messages. - Discontinuous blocks linearized at an operating point near a discontinuity. If such
blocks are not treated as a gain during linearization, the software generates diagnostic
messages regarding their linearization. - Blocks with least one input/output pair that linearizes to zero and that causes a zero
input/output pair in the overall model linearization. A linearization has a zero input/
output pair when a change in an input signal value does not produce a corresponding
change in an output value. - Blocks that do not support linearization because they do not have a predefined exact
linearization and do not support numerical perturbation.
Some diagnostic messages propose solutions to their corresponding linearization issues.
For example, when an input signal is outside the saturation limits of a Saturation block,
the diagnostic message proposes treating the block as a gain during linearization.4 Troubleshooting Linearization Results
