  • Page 26: Autotuning Of Pid Parameters

    12.4.2.1. PID REGULATION The PID algorithm enables achieving smaller control errors (e.g. temperature) than the ON-OFF method with hysteresis. However, the algorithm requires selecting the characteristic parameters for the specific controlled object (e.g. a furnace). In order to simplify the operation, the controller is provided with the advanced PID parameter selection functions described in chapter 12.4.2.2.

In order to avoid unnecessary activation of tuning, which may slow down the process, it is recommended to set the highest possible value of the assigned Hysteresis H, not less than 10÷30% of the range of variability of the process (e.g.

    12.4.2.3. CORRECTION OF PID PARAMETERS The automatic tuning function correctly selects the PID regulation parameters for most processes; however, sometimes it may be necessary to correct them. Due to the strong correlation between those parameters, only one parameter should be changed in the selected Set of PID parameters and the impact of the change on the process should be observed: a) oscillations around the threshold - increase the Proportional band Pb or the Integration time constant Ti, decrease the Differentiation time constant Td (or reduce by a half the Pulsing period Tc for the output)
