This paper deals with the so-called SSDI technique which is a semi-passive approach developed to address the problem of structural vibration damping. This technique takes advantage of an original non-linear processing of the voltage generated by piezoelements. It was shown that the original control law corresponding to the SSDI technique was optimal in the case of mono-modal solicitations. In the case of wide band multi-modal solicitation it is not ever true. This paper proposes a novel multi-modal control law for the SSDI technique. It is based on a probabilistic description of the piezovoltage and results in an optimization of the energy dissipated in the nonlinear device connected to the piezoelectric elements.
