Question

10.4. Given the process reaction curve in Figure Q10.4, calculate initial PID controller tuning constants using the Ziegler-Nichols tuning rules. Compare the results to values from the Ciancone correlations and predict which set of values would provide more aggressive control. 4°C 5% valve position 0 200 Time FIGURE Q10.4

Step 1

- From the process reaction curve in Figure Q10.4, determine the dead time (L) and the time constant (T). Dead time is the time delay before the output starts to respond after a step change in input. The time constant is the time it takes for the process output Show more…
