This work deals with the automatic control of an active vibration damping system . The basic mechanical system is made of two motors driving two unbalanced masses. This equipment, tied to the axe, creates an antagonistic vibration . This torque can be tuned to be exactly opposite to the initial vibration . However, a direct measure of the characteristics of the initial vibration is not available . Thus, it is crucial to get a real time estimation of the vibration parameters (frequency and phase) from the residual torque . The identification is performed by means of extended Kalman filtering based on a special convenient model. At the same Lime, the control law of the motors is implemented .L'étude présentée ici consiste à définir le...
