Commissioning
PID Tuning Calculator
Calculate controller tuning parameters from open-loop step test data using multiple methods.
For reference only — always verify tuning parameters on-site during commissioning. Start with conservative values and increase gain incrementally. These calculations assume a first-order-plus-dead-time (FOPDT) process model.
