OPTIMIZATION Self-optimization Oscillation method Self-optimization SO establishes the optimum controller parameters for PID or PI controllers.
OPTIMIZATION NOTE With output type “solid-state”, the cycle time during optimization is reduced to 8 x the sampling time. With the “relay” output type, care has to be taken that the process value is not influenced by the switching cycle time, otherwise optimization cannot be completed successfully. Solution: Reduce the cycle time Cy, until the process value is no longer influenced.

OPTIMIZATION Check of the optimization The optimum adaptation of the controller to the process can be checked by recording the start-up phase with the control loop closed. The diagrams below indicate possible adjustment errors and how these can be corrected. The control response of a third-order control loop of a PID controller is shown as an example. However, the procedure for adjusting the controller parameters can also be applied to other control loops.
