Abstract
Abstract In this paper simulation and experimental results of Strain rate feedback for active vibration control of a cantilever beam are presented. The piezoelectric patches are fixed on the surface of the host beam based on the Harmonic and Modal analysis done in a Finite Element tool (ANSYS). The dynamic model of the smart beam for the first two modes is obtained using a System Identification technique. The feedback control algorithm is analyzed and is implemented in real-time using National Instruments cRIO 9022 controller. It is observed that with this feedback law 49.29% and 52.84% reduction are obtained for first and second modes of vibration respectively. The result verifies the effectiveness of the controller to suppress the vibration of the smart beam.

Undesired noise and vibrations have a detrimental effect in many areas. Hence the control of vibrations has become a relevant technological challenge. Active vibration control of structures using smart materials is especially in vogue. This involves sensing the motion of the structure using sensors, generating a control signal using a controller and applying a control force on the structure using actuators. To design the control system of any vibrating structure, the mathematical model of the sy...

Active vibration control is an important problem in structures. One of the ways to tackle this problem is to make the structure smart, adaptive and self-controlling. The main objective of active vibration control is to reduce the vibration of a system by automatic modification of the system's structural response. This work features the modeling and design of a robust decentralized controller for a smart flexible system using a periodic output feedback control technique when there is a failure of...

In this paper, a performance criterion is proposed for the optimization of piezoelectric patch actuator locations on flexible plate structures based on maximizing the controllability grammian. This is followed by the determination of parameters required for actuator location optimization through Structuring Analysis in ANSYS Finite Element Analysis Package. Genetic Algorithm is then used to implement the optimization. Finally, with the actuators bonded on optimized locations, a filtered-x LMS-ba...

A study on active vibration suppression for a flexible structural beam via a system identification approach was experimentally performed. The beam, incorporating a pair of piezoceramic transducers as actuators and a set of surface-bonded strain gauges as sensors, was evaluated. The relationship between the input control voltage applied on the actuators and the consequently induced strain, measured by the sensor, was then derived. An active control system, considering both the actuators and senso...

This paper is aimed to develop a feedback controller that suppresses vibration of flexible structures. The controller is designed to minimize the spatial H/sub /spl infin// norm of the closed-loop system. This technique guarantees average reduction of vibration throughout the entire structure. A feedthrough term is incorporated into the truncated flexible-structure model to compensate for the neglected dynamics in the finite-dimensional model. Adding the feedthrough term reduces the uncertainty ...

In this research, a new method based on the equivalence of modal characteristics, differential flatness (DF), and active disturbance rejection control (ADRC) is proposed for the stabilization control of the long flexible arm (LFA). There are two major problems in the system of the LFA. The first problem is that the LFA is very prone to the multiple-mode coupling, while the control systems need as few sensors as possible. Another problem is that the structure of the LFA in practice is often compl...

One of the inherent limitations of adaptive regressor control is that the control system would degrade if the host system has unmodeled dynamics. Whereas, adaptive approximation control has the potential for controlling the host system in the presence of external/internal disturbances. Accordingly, this paper is concerned with a combination of both the regressor and approximation techniques for adaptive vibration control of smart beam. The idea behind this paper is to partition the equation of m...

Smart beams are one of the most frequently used means of studying vibrations in airplane wings. Their mathematical models have been so far solely based on classical approaches that ultimately involve integer order transfer functions. In this paper, a different approach towards modeling such smart beams is considered, an approach that is based on fractional calculus. In this way, a fractional order model of the smart beam is obtained, which is able to better capture the dynamics of the system. Ba...
