“…Vibration control technologies have become increasingly important to improve performance, downsize, and reduce the weight of mechanical systems in recent years. Active vibration control, which can obtain high vibration suppression performance, is widely studied [1] [2]. Many theories and control techniques have been applied to complex vibration problems, including classical control theory such as PID control, modern control theory such as linear quadratic regulators, as well as adaptive control and model predictive control [3] [4].…”

“…The LQR state feedback method provided the best vibration suppression compared to the derivative control and PD control. [7] direct output feedback based active vibration control has been implemented on a cantilever beam using Lead Zirconate-Titanate (PZT) sensors and actuators. Three PZT patches were used, one as the sensor, one as the exciter providing the forced vibrations and the third acting as the actuator that provides an equal but opposite phase vibration/force signal to that of sensed to damp out the vibrations.…”

Abtract-This paper presents design controllers by using control strategies and (LMI) in order to attenuate the vibrations of a beam. An Aluminum beam with fixed-fixed configuration was chosen as an application example of (AVC) of structure. Six conditions had been taken for (AVC) of the beam. In each condition the beam was the same, the changes was in the actuator and in the disturbance according to the location and the kind of the force applied. The attenuation in vibrations of this beam is in maximizing the decay rate (increasing the damping) and limiting the amplitude of the Beam. In this study Pzt actuator had be used, this Pzt have some constraints in the maximum voltage that can be applied, so the input signal must be bounded and limited to some value. In the result there are four requirements for (AVC), stability, input peak bound, output peak bound, and maximizing the decay rate. These requirements had been formulated in the form of (LMI). These (LMI) can be solved by using The Method of Centers For Minimizing The Eigen values. Once the problem solved, the response of the system in the time domain and in frequency domain had been plotted with controller and without controller. The percentage of reduction in the settling time for condition one was (75.9%), while for condition four was (94.6%) and for condition five was (88.32%). The settling time for conditions two and three had increased which means these two conditions are not useful for active vibration control

“…The theoretical finite element modeling is obtained by coupled efficient layer wise (zigzag) theory. Reference [4] presented output feedback based on active vibration control has been accomplished on smart structure (cantilever beam) used Lead ZirconateTitanate (PZT) actuators and sensors to remove from mechanical system undesirable vibrations during their operations. Three PZT patches were used, one as the shaker providing force vibrations, one as the sensor and the third as the actuator.…”

Stability analysis of any precision mechanical system is an important issue to be managed. In the present work two methods of active vibration control had been studied on Unmanned Aerial Vehicle's Wing, controllers P, PI and velocity feedback (VF) were tested to enhance the stability of tested wing. Many types of unmanned aerial vehicles are used in applications required high stability like video recording for meteorological or space research, so attenuation of wing's vibration will improve the performance of camera and will facilitate guiding of the vehicle.
