Sliding mode control of structural vibrations via active-passive hybrid piezoelectric networks

摘要

The purpose of this research is to address the issue of nonlinearities in APPN (Active-Passive Hybrid Piezoelectric Networks) based systems. Experimental effort is carried out to quantify the high order nonlinearity and hysteresis in piezoelectric actuation. Based on the sliding mode control theory, a robust controller is developed to compensate for the nonlinearities and uncertainties in the integrated system. The effectiveness of the proposed scheme is demonstrated by a numerical example.
