(DE) METHOD FOR CONTROLLING A COMBUSTION APPARATUS AND CONTROL DEVICE
Abstract:
(EN) A method for controlling a combustion apparatus having a combustion state in which a parameter related to the combustion state reflects a chaotic behavior is provided. The method includes the steps of measuring the parameter and determining a time series of the parameter, shifting the time series by a variable time delay for determining a time-shifted signal, and forming a difference between the time-shifted signal and the time series for determining a time dependent first signal, so that a norm of the difference is lowest. A time dependent second signal is determined, wherein determining the time dependent second signal includes at least one of using a frequency of a desired oscillating combustion state, and shifting the time series by a set time delay. The first signal and the second signal are combined to determine a control signal. The control signal is used to influence the combustion apparatus.
(FR) L'invention concerne un procédé de commande d'un appareil de combustion ayant un état de combustion dans lequel un paramètre relatif à l'état de combustion reflète un comportement chaotique. Le procédé comprend les étapes consistant à mesurer le paramètre et à déterminer une série chronologique du paramètre, à décaler la série chronologique par un retard temporel variable pour déterminer un signal décalé dans le temps et former une différence entre le signal décalé dans le temps et la série chronologique pour déterminer un premier signal dépendant du temps, de telle sorte qu'une norme de la différence soit la plus faible. Un second signal dépendant du temps est déterminé, la détermination du second signal dépendant du temps comprenant l'utilisation d'une fréquence d'un état de combustion oscillant souhaité et/ou le décalage de la série chronologique par un retard de temps défini. Le premier signal et le second signal sont combinés pour déterminer un signal de commande. Le signal de commande est utilisé pour influencer l'appareil de combustion.
