PID Control for PLC Engineers
From on/off to a tuned loop: what P, I and D each do, how to tune by hand and by rule, anti-windup and filtering, and PID inside Allen-Bradley controllers.
- Explain why on/off control cannot hold a setpoint on a fast process
- Wire a loop's transmitter and final element on Micro800 and MicroLogix
- Predict what raising gain, shortening reset or adding rate does to a loop
