14 - TUNING
Tuning operation allows the setting of optimal PID parameters
in order to assure good control action:
-Stable, “straight-line” control of temperature around setpoint,
without fluctuations;
-quick response to deviations from setpoint caused by external
noises
Tuning involves calculating and setting of the following
parameters:
• Proportional band (inertia of plant; expressed as °C for
temperature)
• Integral time (determines the time taken by the controller to
remove steady-state error signals, Inertia of plant expresses
as time value);
• Derivative time (reaction of controller to change of
measured value, usually ¼ of integral time)
Setpoint value cannot be modified during Autotuning.
