Control Loop Foundation

The Control Loop Foundation web site may be used to gain practical experience by performing workshop and application exercises. Once a workshop or application is selected, then you may access the associated directions. Also, an interactive workspace is provided to perform the lab. The dynamic process simulations used for these workshops provide an environment that …

PID Feedback Control

Many processes have measured and unmeasured disturbance inputs that can significantly impact the value of the controlled and constraint outputs. Process plants are often quite complex and it is not possible for the operating staff to safely and efficiently control the process manually during normal operation. The most common means of providing automatic feedback control …

Measurement and Valve Errors – Sources and Impact

For purposes of analysis of the impact on industrial process control, the sources of a PID input error (deviation between the true process variable and the measurement signal) and a PID output error (deviation between valve-VFD signal and actual stroke-speed) are (Measurement-Valve-Errors.pdf): (1) Offset (2) Drift (3) Nonlinearity (4) Interference (5) Noise (6) Hysteresis (7) …
