3 cards from this section. Quick, good the night before a test.
Define a dominant pole.
Think about which pole influences the response the most.
What is a Bode plot used for?
Consider visual representation of gain and phase.
What effect does shifting a dominant pole to a higher frequency have?
Think about the relationship between pole location and stability.
True or False: Complex conjugate poles always indicate instability.
Consider where these poles are located.
Given a feedback system with poles at 1 rad/s and 10 rad/s, evaluate what happens if one pole shifts towards the other. Discuss the stability implications.
Consider what you learned about pole proximities and stability.
Sketch a Bode plot for a system with a single dominant pole and a complex pole pair. Describe the gain and phase behavior.
Reflect on how feedback systems typically exhibit responses on Bode plots.
