Abstract : Open loop tuning techniques to determine the values of controller tuning parameters generally use a first-order lag plus dead time model fitted to the open loop process step response (process reaction curve). When the process is of higher order, inaccuracies in the fit of the model will result in inaccurate controller parameters. Therefore it is often found that the response of the process can be improved by 'tinkering' with the parameter adjustments of a controller tuned by these methods. A method is presented in this article which assures near-optimal controller settings beginning with the set of controller parameters based on information obtained from open-loop response methods.
