The present invention relates to a method for performing closed-loop control of process-engineering processes, in which setpoint value trajectories are provided for closed-loop control variables, closed-loop control variables and further state variables of the process are detected, control errors are calculated and closed-loop controller manipulated variables are calculated therefrom by means of a control algorithm, and in addition pilot controller manipulated variables are determined, resulting manipulated variables are calculated from closed-loop controller manipulated variables and pilot controller manipulated variables and are set in the process, wherein the structure of the control algorithm and/or of the pilot control are/is changed as a function of closed-loop control variables, further state variables and/or setpoint value trajectories. Furthermore, the invention relates to a closed-loop control device and to a computer program for carrying out the method.
