• Triggered Subsystems-- Triggered Subsystems, Triggered-Enabled Subsystems, Function-Call Subsystem, and other event-based conditionally executed Subsystems will not linearize correctly, since a trigger is an event that is defined by the level of a signal in the past and the current time, so they do not exhibit continuous behavior. Note that Enabled Subsystems are supported for linearization in Simulink 5.0 (R13) and later, and action subsystem (If-Then-Else, Switch-Case) are supported for linearization in Simulink 6.0 (R14) and later.
• Integrator blocks with externally supplied initial conditions-- The block driving the Integrator initial condition port must be an Initial Condition (IC) block or a Constant block. For more information, see the following Related Solution 1-OERRA.
• Continuous or discrete integrator blocks which are near the saturation point-- For example, an Integrator block with an initial state of 90, an input of 1, and an upper limit of 90 will give problematic results since the block's linearization is numerically computed. If your model is near at a saturation point it is best to turn off the "Limit Output" checkbox before linearizing.
