Abstract: The invention relates to a method for automatic regulation of a system in which a plurality of parameters characteristic of the system are measured and in which at least one control parameter (u) is applied as a function of the measured parameters (y). The method includes choosing a nominal operating point of the system, and defining a nominal model (Mn) of the system at this nominal operating point is determined, and estimated characteristic output parameters (yr) corresponding to measurable characteristic parameters (y) are determined from said nominal model. The method further includes determining errors between at least one of the measured characteristic output parameters (y) and at least one of the estimated characteristic output parameters (yr), and applying at least one control parameter of the system as a function of the errors determined to reduce the error between at least one of the estimated characteristic output parameters (yr) and the corresponding at least one measured value of the measured characteristic output parameters (y).

Abstract: The invention relates to a method for automatic regulation of a system in which a plurality of parameters characteristic of the system are measured and in which at least one control parameter (u) is applied as a function of the measured parameters (y). The method includes choosing a nominal operating point of the system, and defining a nominal model (Mn) of the system at this nominal operating point. The method further includes determining a set of representative models ([Mk]) of the possible variations relative to the nominal model (Mn) and parameterizing the error of the nominal model (Mn) of the system by decomposition ([δik]) over all the errors between the models of the set of models ([Mk]) representative of the possible variations and the nominal model (Mn). The method also includes minimizing a given optimization criterion (J) by varying at least one of the previously obtained parameters ([δik]) of the error (Δ) relative to the nominal model (M) of the system. The invention also relates to the regulation device configured for applying the method.
