Question 1.
What is the frequency domain used for in control systems?
Show hintHide hint
Think about how the system output behaves with varying inputs.
Question 2.
What does a Bode plot illustrate?
Show hintHide hint
Remember, it has two parts!
3Question 3.
What does evaluating the transfer function at s=jω allow us to find?
- Time response
- Magnitude and phase
- Input amplitude
Show hintHide hint
Focus on how frequency affects system behavior.
4Question 4.
T/F: Nyquist plots are designed to analyze the gain of a system.
- True
- False
Show hintHide hint
Consider what each plot type is meant to reveal.
Question 5.
Design a feedback control system using a given unstable transfer function. Analyze the stability using both Nyquist and Bode plots.
Show hintHide hint
Focus on how changing parameters impacts the plots.
Question 6.
Explain the impact of several poles in the right half of the s-plane on frequency response and suggest corrective actions.
Show hintHide hint
Consider how feedback mechanisms can stabilize the system.
