Challenge Problems
Push your limits with advanced challenges
If G(s) = 5/(s^2 + 2s + 5), calculate G(jω). Plot the Nyquist plot and determine the system's stability.
💡 Hint: Look carefully at how ω affects the plot shape.
Analyze G(s) = 3/(s^3 + 3s^2 + 3s + 1) by constructing its Nyquist plot. Explore how varying K affects stability.
💡 Hint: Consider the relationship between K and encirclements around -1.
