摘要：

This paper presents the design and the experimental implementation of fast and periodic output feedback controllers to minimize structural vibration, using collocated piezoelectric actuators and sensors. A linear dynamic model of the smart cantilever beam is obtained using online recursive least squares parameter estimation. A digital control system that consists of simulink modeling software and a dSPACE1104 controller board has been used for identification and control. The effectiveness of the controllers is shown experimentally by exciting the structure at resonance.
