Steuerverfahren mit einer durch Stützpunkte definierten Kennlinie

摘要

The invention relates to a control method with a characteristic curve which is defined by interpolation points (3, 4, 5, 6, 7), said characteristic curve being stored in an electronic processing unit. The aim of the invention is to provide a stable, sufficiently accurate method for controlling processes which are overridden by strong, time-variant disturbances. To this end, the characteristic curve (1) provided is adapted in accordance with a system deviation and a ratio of the difference between a measured point (9) and an adjacent interpolation point (4, 5) and the difference between the two interpolation points (4, 5) adjacent to the measured point (9).
