4-9-2 RT (Robust Tuning) (Used for Autotuning)
z RT Features
• Even if hunting occurs for PID constants when autotuning is executed in normal mode, it is less
likely to occur when autotuning is executed in RT Mode.
• When the temperature (PV) falls short of the set point for the PID constants when using
autotuning in normal mode, executing autotuning in RT Mode tends to improve performance.
• When the manipulated variable (MV) is saturated, the amount of overshooting may be somewhat
higher in comparison to PID control based on autotuning in normal mode.
This procedure selects RT mode.
Operating Procedure
