PID Monitor

PID Monitor

Real-Time control loop performance monitoring

PID Monitoring is software that monitors the control loops (usually PID loops) to check their health. Health indicators include:

  1. Loop Oscillations / Instabilities: Be notified when loop oscillations are detected
  2. Backlash: Get an estimation of the amount of backlash in the actuator
  3. Actuator Saturation: Actuator saturation may indicate a not-in-control process
  4. Loop damping: over-damping indicates the loop performance can be improved.

Description of the software package

The PID Monitor can either run in the cloud (Azure) or on a dedicated local server. The PID Monitor has the following features:

  • Historical Trending: Uses OPC the retrieve data, and store it in an InfluxDB database.
  • Loop Performance Monitoring: Allows the PID Monitor to automatically detect issues with the control loop performance, such as:
    • Backlash: Get an estimation of the amount of backlash in an actuator
    • Oscillations: Oscillations may indicate bad tuning, and or loop instability
    • Actuator Saturation: May indicate a not-in-control process
    • Control Bandwidth: May be caused by changes in the process gains.
    • Damping Estimation: Estimate the closed-loop damping of a control loop. A low damping value may indicate issues.

Customer reviews

”The automatic notifications really helped us to quickly and pre-emptively find root-causes of issues in our process, reducing trips and downtime”
