A method of controlling a process having a plurality of independently controlled, manipulated variables and at least one controlled variable which is dependent on the manipulated variables. In the first step of the method data is gathered about the process by introducing test disturbances in the manipulated variables and measuring the effect of the disturbances on the controlled variable. The value of the controlled variable is measured at a first time. Using the data gathered from the test disturbances and the measured value of the controlled variable, a first set of changes in at least one of the manipulated variables is calculated such that the controlled variable is driven towards its set point without exceeding a predetermined limit. The manipulated variables are adjusted in accordance with at least one change from the first set of calculated changes. The values of the manipulated variables and the controlled variable are then measured at a second time. A second set of changes in at least one of the manipulated variables is calculated using the first set of changes and the measured values at the second time. This second set of changes is calculated such that the controlled variable is driven towards its set point without exceeding a predetermined limit. The manipulated variables are adjusted in accordance with at least one change from the second set of changes.
