The invention relates to methods and devices (100) for controlling a controlled variable of a controlled
system (110) with a fluidic drive, in particular of controlled systems (110) with an excessive air output capacity. Controlled systems (110) with excessive drive are often controlled with the aid of rate limiters (170), which prevent an overreaction. If, however, the systems (110) have pronounced delays or
hysteresis, a rate
limiter (170) may often not prevent an overreaction. Proposed for solving this problem are methods and devices with which delays or
hysteresis are detected on the basis of changes in the actual value of the controlled variable and are taken into account in the
rate limiting. In particular, the value of the air output capacity is used to quickly overcome states that are characterized by delays or
hysteresis. As soon as the states have been overcome, the
rate limiting is raised in order to prevent an overreaction of the controlled
system (110). In this way, dead times can also be reduced.
