Process reaction curve method of tuning is done for a system in

• A. open loop
• B. closed loop
• C. interacting loop
• D. non interacting loop

Hint:

Ziegler-Nichols has two methods:
1. Process Reaction Curve Method: Done in open loop using step response.
2. Continuous Oscillation Method (Ultimate Gain): Done in closed loop by bringing the system to its stability limit.
