In this paper, the performance of a semi-active control of structural vibrations which is the Synchronized Switch Damping on Inductor Max called SSDI-Max technique is improved. This improvement is achieved by adding a negative capacitance to the resonant circuit that dissipates the energy converted from the structure by the piezoelectric transducer. A model of system shunted to a resonant circuit, using the SSDI-MAX control and the negative capacitance, is analyzed analytically using Matlab/SIMULINK environment. The results show that a light modification with the same used energy can highly increase damping performances.
