Vibration Control of Smart Structure Using Sliding Mode Control with Observer

This paper studies the application of the sliding mode control method to reduce the vibration of flexible structure with piezoelectric actuators and strain gage transducer in practical complex environment. The statespace dynamic model of the system was derived by using finite element method and experimental modal test. The structure is subjected to arbitrary, unmeasurable disturbance forces. Ta...

Active Vibration Suppression of a Smart Beam via PID Control

In this study, a PID controller was designed for the active vibration suppression of a smart beam equipped with PZT (Lead-Zirconate-Titanate) patches. The smart beam is a cantilever aluminium beam having eight symmetrically located surface-bonded piezoelectric patches. In this particular application, a group of PZT patches closed to the root of the beam was used as actuators and from the remain...

Efficiency of Active Control of Beam Vibration Using PZT Patches

This study is aimed to explore efficiency problems of using PZT patches in active vibration control of beams. The PZT patches are surface-bonded as actuators and strain gages are used as sensors. Distributed moment forcing mode is adopted to derive the control authority of actuators. Uniform beam model is applied when the mass and stiffness of PZT patches are ignored. Stepped beam model is then...

Title: Active Vibration Suppression of Smart Structures Using Piezoelectric Shear Actuators

Current active vibration suppression systems usually consist of piezoelectric extension actuators bonded to the surface or embedded within the structure. The use of piezoelectric shear actuators/sensors has been proposed as an alternative, where the electric field is applied perpendicular to the direction of polarization to cause shear deformation of the material. We present an exact analysis a...
