Challenge Problems
Push your limits with advanced challenges
Given a feedback system with poles at p1 = -1 + 2j and p2 = -1 - 2j, analyze the stability of the system and potential for oscillatory behavior. What changes might occur if p1 and p2 get closer to the real axis?
💡 Hint: Consider the implications of pole locations and their relative distances.
You design a feedback amplifier with a dominant pole p1 at -1 and another at p2 at -3. If a feedback loop shifts p1 to -2, should you expect an improvement or degradation in system stability? Justify your answer.
💡 Hint: Reflect on the definitions of dominant poles and their influence on behavior.
