To reduce the process variable error, the closed-loop control function in PID controllers is commonly used. A PID controller reads a process variable (PV), compares it to a desired set point (SP) ...

For setpoint changes, the Smith Predictor outperforms a deadtime-compensated PI controller, but not a PID controller with ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...
