Extract Output Elements of Feedback System

This example demonstrates how to extract the output elements of a state-space system that uses vector signals.

Open the example model.

mdl = "FeedbackSystem";
open_system(mdl)

These equations define the state-space system:

$$\underset{}{\overset{\dot{}}{x}}=Ax-BKx+Bu$$

$$y=Cx$$

To ensure that the system is stable, the state feedback vector $$K$$ is chosen such that the eigenvalues of $$A-BK$$ equal $$-1+i$$, $$-1-i$$, $$-2$$, and $$-3$$.

The Demux block extracts the two elements from the output vector $$y$$. Then, the Scope block separately plots each element it receives.
