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

[an error occurred while processing this directive]

 

• 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.
