Patent ID: 7474927

Claim:
A method for optimizing control parameters, comprising: experimentally ascertaining an initial transfer function of a transformer that includes a control structure and a black box as a system to be controlled; deriving quality criteria from the initial transfer function of the transformer, the quality criteria used to optimize the control parameters; and following a modification of the control parameters, calculating a modified transfer function from the initial transfer function of the unmodified transformer without a new experimental identification; wherein a controller of the control structure and the black box are series connected, and the modified transfer function is calculated in the calculating step according to the relationship: F o ′=F o K′/K=BB*K; F o ′ representing the modified transfer function, F o representing the initial transfer function, K representing an initial transfer function of the controller, K′ representing a transfer function of the controller after the modification, and BB representing a transfer function of the black box.
