20080319725 | Method of Estimating the Instantaneous Engine Speed Produced by Each Cylinder of an Internal-Combustion Engine - The invention is a method for real-time estimation of the instantaneous engine speed produced by each cylinder of an internal-combustion engine, from an instantaneous engine speed measurement at the end of the engine transmission system. A physical model, representing in real time the dynamics of the transmission system according to the crankshaft angle and to coefficients of a Fourier series decomposition of the instantaneous speed produced by each cylinder, is constructed. These coefficients are determined in real time from coupling between the model and an adaptive type non-linear estimator. The instantaneous speed produced by each cylinder is then deduced from these coefficients. The mean torque produced by each cylinder can also be deduced therefrom. An application is: engine controls. | 12-25-2008 |

20100264861 | METHOD FOR DETERMINING THE POSITION OF THE FLUX VECTOR OF A MOTOR - The invention relates to a method for determining the position of a rotor flux vector of an electric motor (M), comprising a step of injecting a first current vector into a first reference frame (x | 10-21-2010 |

20110249479 | METHOD OF CONTROLLING AN INVERTER OF NPC TYPE - The invention relates to a method of controlling a multilevel inverter of NPC (Neutral Point Clamped) type. The method consists in particular in regulating the electrical potential of the mid-point when the inverter operates at full voltage, that is to say in overmodulation. In this case, the method firstly consists in determining the position of the control voltage vector (U) in one of the six identical triangles covering the hexagonal vector space and thereafter in decomposing the control voltage vector (U) in the triangle by taking account of the control combinations, defined in this triangle, for the switching arms. | 10-13-2011 |

20130334992 | CONTROL METHOD IMPLEMENTED IN A POWER CONVERTER AND INTENDED FOR IDENTIFYING PARAMETERS LINKED TO THE MAGNETIC SATURATION OF AN ELECTRIC MOTOR - A control method implemented in a power converter including an inverter connected to a synchronous electric motor including permanent magnets, the electric motor being modeled in the power converter by a mathematical model of currents in the electric motor expressing a flux current and a torque current on the basis of magnetic-saturation parameters. The control method identifies magnetic-saturation parameters during a learning procedure including applying a static voltage signal and a high-frequency voltage signal along an axis of the flux and/or an axis of the torque of the motor to cause an oscillation of the current on the axis of the flux and/or on the axis of the torque. | 12-19-2013 |
