Simulink® Control Design™

Linearizing a Block

With the Simulink^® Control Design™ software you can also linearize a single block in a Simulink^® model. To do this, right-click the block and select Linearize Block from the context menu.

This adds a Block Linearization Task node to the project tree as shown in the following figure.

To complete the linearization, specify an operating point in the same way as when linearizing models. See Linearizing Models in the Control and Estimation Tools Manager for details. Then, click the Linearize Block button in the Operating Points pane of the Block Linearization Task node. You do not need to choose linearization input and output points because the inports and outports of the block are used. If you do have linearization input and output points in your model, they will be ignored. You cannot linearize an individual block using numerical-perturbation linearization (when Numerical perturbation is selected as the Linearization Algorithm parameter).

Note   To be linearized, an individual block must contain at least one data inport and outport. Blocks from products based on the Simscape™ platform and SimPowerSystems™ blocks have connection ports instead of inports and outports. Thus, they cannot be individually linearized.
