A method of optimizing the power recovered by a wind turbine by reducing the mechanical impact on the structure is disclosed. A first angle of inclination of the blades allowing the recovered power to be optimized is determined. The aerodynamic force produced on the nacelle when the blades are directed with a first angle is determined. A second angle of inclination of the blades allowing obtaining an aerodynamic force setpoint value is then determined by inverting the aerodynamic force model and using a wind velocity measurement, a rotor velocity measurement and the aerodynamic force setpoint value. Finally, the blades are directed to the second angle.

The invention relates to a method for diagnosing a particulate filter by means of a soot sensor, the method being based on the direct analysis of the temporal signal supplied by the soot sensor (CAP) and the use of the available quantities (PAR) in the control unit of the heat engine. These data allow for a classification (CLA) of an indicator correlated to the cumulative quantity of soot (RES) in a multidimensional space (GRA). Based on the classification (CLA), the existence of a failure of the particulate filter is determined.

The invention relates to a method and a system for controlling the production of a mixture of constituents, especially a mixture with premix dead volumes. By correcting the matrices for calculating the mixture constituents, used in calculating recipes, by introducing limit, order relationship and equality constraints, it is possible to avoid the drifts observed in certain special cases by the implementation of the method and to improve, on the one hand, the diagnostic assistance and the control of the estimation of the properties so as to limit the deviations from the actual quality of the constituents of the mixture and, on the other hand, the speed of manufacture of the mixture and the robustness of the method. The method and the system according to the invention ensure multivariable regulation feedback by a dynamic observer providing an estimate in real time of the properties of the constituents of the mixture, said estimate being sufficient to guarantee the effectiveness of the feedback loop.

The invention relates to a method and a device for controlling the production of a mixture of components, especially a mixture with premix dead volumes. The method and the device according to the invention ensure multivariable regulation feedback by a dynamic observer providing an estimate in real time of the properties of the components of the mixture, said estimate being sufficient to guarantee the effectiveness of the feedback loop. Thus, the desired properties of the mixture are guaranteed despite large uncertainties in the properties of the components on the one hand, and partial knowledge of the mixing process on the other.

Method of controlling the active regeneration of a particulate filter through dynamic control of the temperature at the outlet of an oxidation catalyst. A control law is defined for a hydrocarbon flow rate at the oxidation catalyst inlet, by means of the ratio between a temperature demand and a gain. The gain can be corrected so as to take account of the transient phenomena that occur in the oxidation catalyst during a gas flow rate variation. The temperature demand can comprise a precompensation term to compensate for the effects of a temperature variation at the oxidation catalyst inlet. The temperature demand can comprise a feedback term calculated by a controller whose parameters are automatically calculated by means of a physical model of the catalyst, during operating conditions variations. Any combination of these terms allows to define a suitable control law. Finally, the hydrocarbon flow rate is modified by applying the control law so that the temperature of the gas leaving said catalyst respects a set point temperature. Application: engine control.
