Title:
AUTOMATED PARAMETERIZATION OF A CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2020/049051
Kind Code:
A3
Abstract:
The invention relates to a method for the automated parameterization of a multi-variable system which is controlled in a decentralized manner by means of PI and/or PID controllers and is used in the context of a control system of a technical system. The method comprises the following steps: a) determining manipulated variables (U1, U2) and regulating variables (y1, y2) of the technical system, which are provided for a common pairing; b) use of an effective open loop transfer function for calculating suitable initial values for the parameterization of the decentralized PI and/or PID controllers; c) optimizing the parameterization with regard to a quality function.
