Challenge Problems
Push your limits with challenges.
Question 1
A certain control system shows sustained oscillations with Ku = 25 and Pu = 4 seconds. Calculate the PID parameters and discuss any limitations of using these parameters.
💡 Hint: Use the formulas carefully and think about system behavior.
Question 2
Describe how you would approach tuning a PID controller in a real-world scenario where the Ziegler-Nichols method yields oscillations that are too pronounced.
💡 Hint: Consider what adjustments can stabilize the output.
