چکیده
Using strain devices as sensors, and using piezoelectric devices as actuators, the experimental research on the vibration control of large flexible space structures is presented in this paper. The control theory used in this experiment will be introduced. The working principles of the strain devices and the piezoelectric devices will be explained in detail in this paper. A satellite panel system has been taken as an experiment sample. The experiment results show that (1). The control method presented in this paper is effective, (2). The strain device is a suitable sensor due to its small size, light weight, and high precision, (3). The piezoelectric devices is a good actuator due to its small size. light weight, and special piezoelectric characters, (4). The usage a{ microsensors and microactuators in the vibration control is ofpractical value and is o{ many e~pecial advantages for the vibration control a{ large flexible space structures.

The purpose of this paper is control of simply supported flexible core sandwich beam's linear vibration equipped with piezoelectric patches under different loads. The effects of external forces imposed on sandwich beam can be reached to a minimum value by designing an appropriate controller and control the beam's vibration. Three-layer sandwich beam theory is used for analytical modeling of san...
متن کاملActive Vibration Suppression of a Nonlinear Flexible Spacecraft
In this article, the issue of attitude control and active vibration suppression of a nonlinear flexible spacecraft is assessed through piezoelectric patches as actuator and sensors. Two controller loops are applied: the inner loop, to make the panel vibration damped through piezoelectric patches; and the outer loop, to perform spacecraft maneuver using the reaction wheel acting on the hub. An o...
متن کاملResonant frequency of bimorph triangular V-shaped piezoelectric cantilever energy harvester
The concept of “energy harvesting” is to design smart systems to capture the ambient energy and to convert it to usable electrical power for supplying small electronics devices and sensors. The goal is to develop autonomous and self-powered devices that do not need any replacement of traditional electrochemical batteries. Now piezoelectric cantilever structures are being used to harvest vibrati...
متن کاملQFT Control of a Two-Link Rigid-Flexible Manipulator
This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...
متن کاملActive vibration control of smart building frames by feedback controllers
In this paper the active vibration control of a four-story shear frame instrumented with piezoelectric actuators is presented. The piezoelectric actuators are hosted on the columns in two manners and the produced controlling forces by actuators are considered in the equation of motion. The smart structure modeling and control design is carried out using MATLAB software in state space form. Subs...
