Patent ID: 7692502

Claim:
A method for controlling an oscillatory system having at least one measurement variable, by detection of at least one oscillation component (S(t)) over the time (t) in the form of at least one measurement variable; characterized by determination of a controlled variable (δ u ) for controlling the oscillatory system from the sum of the weighted differences of the oscillation component (S 1 (t−τ 1 ),S 2 (t−τ 2 )), which has been delayed in the case of one measurement variable at least twice by different delay times (τ 1 >0, τ 2 >0), and its respective undelayed oscillation component (S 1 (t) and S 2 (t)), and in the case of a plurality of measurement variables, oscillation components (S i (t−τ i )), which have in each case been delayed at least once by a specific delay time (τ i >0), and their respective undelayed oscillation components (S i (t)) using the relationship S u =a 1 S 1 ( t )− b 1 S 1 ( t−τ 1 )+ . . . + a n S n ( t )− b n S n ( t−τ n ), where a 1 , . . . , a n and b 1 , . . . , b n are weighting factors for the oscillation components S 1 , . . . , S n of the measurement variables.
