Research of Hysteresis Compensation Modeling of PZT Patches and Active Vibration Control of Cantilever Beams
摘要
Abstract
In order to improve the vibration control effects of the piezoelectric cantilever beams,an inverse hysteresis compensation control method based on least squares algorithm is presented.The displacements of the lead zirconate titanate (PZT) patch under different voltages are measured, and the hysteresis loop model of the PZT patch is fitted with the polynomial via least squares algorithm. Using the inverse hysteretic compensation model of the PZT patch, the control voltage is compensated.Through the active vibration control experiments of the piezoelectric cantilever beam, the control effects of the PID controller with or without inverse hysteresis compensation are systematically studied.The results show that the active control effect of PID controller with inverse hysteresis compensation is 10.083 % higher than the traditional PID controller.Thus, the inverse hysteresis compensation method can effectively improve the active control effects of the PZT patch,which is of great reference value for active vibration control of piezoelectric cantilever beams.关键词
