Fractional-order derivatives and integrals have gained serious attention by the researchers in past few decades. It has been observed that fractional calculus is more suitable in modeling real life systems. In this paper, Fractional-Order PID (FOPID) controller is studied to suppress the vibration of cantilever beam modeled by Euler-Bernoulli model. Finite difference method is applied to analyze the behavior of the system at different fractional orders of PID controller, and the governing equations are simulated using MATLAB. The response of the system is evaluated at different fractionalorder control points, under constant PID parameters (K p , K i , and K d). Furthermore, the variation of frequency in transient response and 5% settling time is observed. Simulation results reveal that, though system with fractional order controller is more flexible now, the classical model of PID controller can also be properly tuned through PID constants to achieve the resultant response of the system. So, due to more simplified modelling, the classical model has an edge over the fractional order in the vibration control of cantilever beam.

We demonstrate the detailed analysis for conversion of piezoelectric properties into compliance matrix and simulate a series bimorph configuration for vibration based energy generation. Commercially available software COMSOL Multiphysics was used to apply boundary conditions for optimization of geometric parameters such as length, width and thickness of piezoelectric layer to study voltage and power characteristics of the harvester. The resulting energy harvester was found to generate 1.73 mW at 53.4 Hz across a 3MΩ load with an energy density of 13.08mJ/cm3. We also investigated feasibility of this model by comparing it with existing experimental data of known piezoelectric ceramic compositions and found good correlation between the two.

“…A key to the problem of vibration damping with shunted piezoelectric elements is to find the parameters of a simplest shunt that is most effective in damping the vibrations of a particular structure at a group of frequencies in the specified frequency range. The shunt circuit should meet the following requirements: it should provide maximum damping of mechanical vibrations and preserve its stability; it should operate without a power source; its design costs and weight should be reduced to a minimum; and, since the circuit is integrated in the structure, the size of its elements should be minimal [3]. Over the last decade, a variety of passive shunt circuits have been designed and rated.…”

“…Over the last decade, a variety of passive shunt circuits have been designed and rated. According to the classification presented in Moheimani and Fleming [3], passive shunts can be linear or nonlinear. Among the linear passive circuits, one can distinguish between the resistive (including only resistors) and resonant (including resistors and inductors) circuits.…”

For the selecting of the parameters of the shunt circuit that provide multimodal damping of vibrations for the corresponding piezoelectric element location an approach is proposed. This technique is based on a solution to the natural vibration problem for an electroelastic structure with an attached piezoelectric element that is shunted with a single external resonant electric circuit. The solution to the problem is complex natural vibration frequencies. The analysis of their behaviour in the space of external circuit parameters (resistance-inductance) allows one to reveal the possibility of natural vibrations control at several frequencies (multimodal vibration damping). The applicability of the proposed approach is demonstrated using a shell structure in the form of a semi-cylinder with a piezoelectric element attached to its surface and shunted with a singlebranched resonant electric circuit. Some options are considered that provide multimodal damping at several separated frequencies, which are not from the complete frequency range, and at all the frequencies, which are included in a specified frequency range.
