A review: The control strategies of synchronized switching damping technique

This review collects and presents the prototype control laws of synchronized switching damping technique, shortly SSD. SSD control law is an algorithm, which processes on the motion of the structure to determine the timing and synchronously trigger the switch device. Since the original control law consisting of triggering switch on each extremum of displacement is only optimal in the harmonic excitation and there is not a almighty algorithm which is able to deal with variant excitations, so different control laws were proposed. In this paper, according to different purpose, analyse the corresponding control laws. The advantages and disadvantages of each strategy are evaluated and conclusions are drawn regarding the relevant merits.
