Abstract

The invention concerns an arrangement for the adaptive control of a section (3) with a signal pre-processing system (4) by means of which sampled values (a) can be generated from the time characteristic of the controlled variable (x), and with a neural network (5) which calculates the parameters (Kp, Tn, Tv) of the controller (2) in dependence on the sampled values (a). The neural network (5) is trained with reference to learned data of the parameters (Kp, Tn, Tv) and sampled values (a) of the section step response, which have been generated by analytically calculated parameter adjusting rules or control circuit simulation and numerical optimization for one or a plurality of section models. The neural network (5) thus supplies the learned data with optimum control parameters which are well-suited to intermediate values owing to its generalization properties. The invention is used in automation technology.
