✦ Synopsis
Vibration control using piezoelectric actuators has experienced a strong development these last years. Particularly, non-linear techniques have been proven to be low-cost and efficient ways of damping, with self-powering capabilities. This paper deals with one of these methods, the so-called self-powered synchronized switch damping on inductor (SSDI). Its principles rely on switching intermittently the piezoelement on a resonant circuit. Particularly, it is proposed here a new self-powered device that enhances the broadband nature of the self-powered SSDI. The principles of the circuit are to disable the switching event unless a particular condition is fulfilled. Experimental results show that such a circuit significantly improves the multimodal control abilities of the self-powered SSDI techniques without any external power supply requirements.
