1 Can you apply Ziegler-Nichols oscillation tuning method to a first order system? Why?

2 Can you apply the reaction curve based tuning rules to unstable systems? Why?

3 How do we decide the sign of the proportional feedback controller gain when using the Ziegler-Nichols oscillation method?

4 Can you envisage any potential danger when using Ziegler- Nichols oscillation method?

5 How do you design a step response experiment?

6 What information will the step response experiment provide?

7 How do you determine steady-state gain, parameter and time delay from a reaction curve?

8 What are your observations when comparing Ziegler-Nichols and Cohen-Coon tuning rules, in terms of signs and values of , and ?

9 Is there any desired closed-loop performance specification among the tuning rules?
