Patent ID: 8095252

Claim:
A method for eliminating oscillations, corresponding to induced pilot oscillations, in a piloting order generated by the action of the pilot of an aircraft on a piloting device controlling a movable aerodynamic surface of said aircraft, said surface being actuated by actuating means, the method comprising: filtering said piloting order by means of a non-linear filter, the filtering function of which comprises at least one filtering parameter; and using a set of piloting laws to determine a control order for said actuating means from said filtered piloting order; wherein: the actual maximum speed of amplitude variation of said control order is estimated; a reference speed of amplitude variation of said control order, compatible with the speed of deployment of said actuating means, is determined such that, when said actual maximum speed is at least approximately equal to said reference speed, said control order is free of oscillations corresponding to induced pilot oscillations; said actual maximum speed is compared with said reference speed in order to determine comparison information; a suitable value of said filtering parameter is determined, based on said comparison information, for which said actual maximum speed is at least approximately equal to said reference speed; and said suitable value is used to modify the current value of said filtering parameter.
