Question 1

What happens when poles in a feedback system are close together?

  • They have no effect.
  • They may lead to complex conjugate poles.
  • They stabilize the system.

💡 Hint: Think about how pole positions affect system behavior.

Question 2

True or False: The dominant pole has the least influence in defining a system's frequency response.

  • True
  • False

💡 Hint: Consider the term 'dominant' in relation to influence.

Challenge Problems

Push your limits with challenges.

Question 1

Design a feedback system with two poles at s = -3 and s = -5. Explain how the location of these poles affects stability and how you would modify them if they were too close.

💡 Hint: Think about the implications of pole positions on system stability.

Question 2

Analyze the Bode plot of a system with a dominant pole at 5 Hz and a second pole at 15 Hz. Discuss the key characteristics displayed in the plot and their implications for system design.

💡 Hint: Reflect on how those characteristics impact real-world applications.
