Patent ID: 8401717

Claim:
A method of generation of a control signal for controlling at least one mechanical system exhibiting at least one flexible structure element and at least one actuator or group of actuators, said method being implemented by calculation and computing means; said method being intended to reduce the level of vibrations of said flexible structure element while controlling said actuator or group of actuators in such a way as to achieve at least one objective assigned to said mechanical system, said control signal comprising increments and energy peaks, each of said increments being either constant in amplitude between two successive sampling instants or applied during an increment application interval of a duration ΔT which is less than or equal to a sampling period T, wherein said method includes at least a step according to which, in each sampling interval, a variable, random or pseudo-random, temporal deviation (dT), termed random deviation is added to at least one of an initial and a final instants of application of said increment, wherein a probability law chosen to determine said random deviation is defined in such a way as to modify at least one of the energy peaks of said control signal.
