21.8 VERIFYING CONTROL SYSTEM STABILITY

---

Introduce random errors to the system model and test for stability

Use the Nyquist Stability Theorem,

21.8.1 Stability

The stability function is defined using the Nyquist plot.

21.8.2 Bounded Gain

In practical terms system gain is limited by real components. As a result it is important to ensure that the design will not exceed the maximum values available.
