“…It can be seen that the exponential time-decay rate is maximized by updating the value of the resistance. Similar studies have been already published for piezoelectric transducers when an active control is used to enhance the electromechanical coupling constant and subsequently improve significantly the passive piezoelectric shunt damping [30,32,34].…”

It has been shown that shunting electromagnetic devices with electrical networks can be used to damp vibrations. These absorbers have however limitations that restrict the control performance, i.e. the total damping of the system and robustness vs parameter variations. On the other hand, the electromagnetic devices are widely used in active control techniques as an actuator. The major difficulty that arises in practical implementation of these techniques is the power consumption required for conditioners and control units. In this study, robust hybrid control system is designed to combine the passive electromagnetic shunt damper with an active control in order to improve the performance with low power consumption. Two different active control laws, based on an active voltage source and an active current source, are proposed and compared. The control law of the active voltage source is the direct velocity feedback. However, the control law of the active current source is a revisited direct velocity feedback. The method of maximum damping, i.e. maximizing the exponential time-decay rate of the response subjected to the external impulse forcing function, is employed to optimize the parameters of the passive and the hybrid control systems. The advantage of using the hybrid control configuration in comparison with purely active control system is also investigated in terms of the power consumption. Besides these assets, it is demonstrated that the hybrid control system can tolerate a much higher level of uncertainty than the purely passive control systems.

“…Therefore, Tsai el al. [34] proposed a methodology to determine the optimal values of the resistor and inductor simultaneously with the control law. Furthermore, the multiple APPN has been also investigated to control of a quadrilateral plate [35] and a ring structure [36].…”

“…With the term hybrid, the authors wish to refer to the simultaneous use, on the same host structure, of both RL and NIC electrical networks. The use of hybrid shunts has been first investigated by Tang and Wang (2001), Tsai and Wang (2002), and Zhao (2010) where the use of the mechanisms was applied to the same patch. The present approach is different in the sense that each patch is shunted with either an RL or an NIC circuit.…”

Periodic arrays of hybrid-shunted piezoelectric actuators are used to suppress vibrations of an aluminum plate over broad frequency bands. Commonly, piezoelectric-shunted networks are used for individual mode control, through tuned, resonant resistive/inductive circuits, and for broadband vibration attenuation, through negative impedance converters. Periodically placed resonant shunts allow for broadband reduction resulting from the attenuation of propagating waves in frequency bands which are defined by the spatial periodicity of the array and by the shunting parameters considered on the circuit. Such attenuation typically occurs at medium–high frequencies, while negative impedance converter networks are effective in reducing the vibration amplitudes of the lower modes of the structure. In this article, the combination of periodic resonant shunts and negative impedance converter networks on the same aluminum panel is studied to verify the possibility of combining the advantages of the two concepts. Both numerical and experimental investigations demonstrate that broadband attenuation is achieved in the mid–high frequency regimes due to the presence of resistive/inductive networks, while the combination with negative impedance converter circuits is responsible for amplitude reduction of the full frequency spectrum. Numerical simulations and frequency response measurements on a plate demonstrate that an attenuation region of about 1000 Hz is achieved with a maximum 8 dB vibration reduction.

“…Piezoelectric patches have also been used for broadband control of continuous systems including the use of collocated control pairs [14][15][16] , hybrid passive control [17][18][19] , and self-sensing techniques. The ability of a piezoelectric patch to be both a sensor and actuator concurrently, or sensoriactutor, was developed by Dosch 20 to estimate the strain in the piezoelectric element.…”

Active vibration control of a stiffened panel through application of negative capacitance shunts

et al. 2011

View full text Add to dashboard Cite

Shunted piezoelectric patches form an effective control mechanism for reducing vibrations of a mechanical system. One type of shunt, a negative capacitance circuit, is capable of suppressing vibration amplitude over a broad frequency range. Most previous work has focused on control of simple test structures such as beams and plates. This work studies the performance of the negative capacitance shunt connected to piezoelectric patches attached to a stiffened aircraft panel. The placement of the piezoelectric transducers is determined using a simplified finite element model of one bay of the panel. The numerical predictions are compared to experimental results for spatial average vibration for a point force input. The amount of control for increasing number of patches is also investigated. These results give a more accurate representation of the achievable performance in real world application.
