Standard PID Tuning Methods
pages.mtu.eduII. Ziegler-Nichols Method (Closed-loop P-ControlTest) Step 1: Determine the sign of process gain (e.g. open loop test as in Cohen-Coon). Step 2: Implement a proportional control and introducing a new set-point. Step 3: Increase proportional gain until sustained periodic oscillation. Step 4: Record ultimate gain and ultimate period: )*+ ,*-).
