<p>The method serves to control sluggishly reacting systems in which rapid changes in set value occur. The controller (4) used has an integrating (I)-section (11) and a proportional (P)-section (20) separate from the I-section (11). The I-section (11) receives a control variation formed from the actual value and the set value, whereas the P-section (20) is supplied with the set value. The output signals of the I-section (11) and of the P-section (20) act on the plant (1). The I-section (11) is blocked or interrupted for the duration of an abrupt change in the set value. As a result of this relatively short interruption in operation of the I-section, the control provided by the plant is improved as compared with a method in which the change in set value acts on the I-section but with a delay determined by a delay element.</p> |
