Abstract :
A method for controlling noise caused by pulsed flow is considered. It consists in rejecting a periodic disturbance whose characteristics are time varying. A time-frequency approach is used. An adaptive recursive ellipsoid algorithm, founded on an OVE algorithm, extended for complex parameters estimation is presented. Associated with a dead-beat controller, it enables adaptive control of the disturbance. Tests of control using this algorithm are effected in simulation
