Abstract

Abstract:

This paper presents the integration research on sensor/actuator and control system of flexible structure, and analyses the active vibrational control system of flexible beam system using piezoelectric sensor/actuator.The measurement equation of piezoelectric sensor and the driver equation of actuator are given. An adaptive filtering technique for active vibration control is provided.The control system is realized by the host slave system which consists of computer 486 and TMS320C25. Experimental results have demonstrated the effectiveness of this kind of control strategy.

Key words: vibration, active control, flexible beam, piezoelectric sensor/actuator
