Semi-active vibration control of the motorized spindle using a self-powered SSDV technique: simulation and experimental study

Abstract

SSD (synchronized switch damping) is used for vibration control of the motorized spindle based on piezoelectric stack. Moreover, inspired by self-powered SSDI, a self-powered SSDV circuit was designed to overcome the disadvantages of requiring readjusting control parameters and sensor re-positioning of SSDI (synchronized switch damping on inductor) and SSDV (synchronized switch damping on voltage source). A simulation and an experimental were built, and the results show vibration control performance of self-powered SSDV is better than self-powered SSDI and is more flexible and effective than self-powered SSDI by adjusting the DC voltage to adapt to different speeds of the motorized spindle.
