A reliable and evolvable vibration suppression technique using a digital processor powered by energy harvested from a piezoelectric element was developed and investigated. This technique, called a self-powered digital vibration control, benefits from both the sophisticated control logic of the digital processor and a reliable self-powered semiactive element. A system embodying this technique consists of a circuit outline, CPU, and DC/DC converter. Two experiments emulating the synchronized switch damping on inductor (SSDI) technique demonstrated its effectiveness for steady inputs as well as transient ones.
