AB  - A novel concept of morphing airfoils, capable of changing camber and thickness, is proposed. A variable airfoil shape, defined by six input parameters, is achieved by allowing the three spinal points (at fixed axial positions) to slide vertically, while the upper and lower surfaces are determined by the lengths of the three corresponding ribs that are perpendicular to the spine. Thus, it is possible to find the most appropriate geometric configuration for a wide range of possible operating conditions often present with contemporary unmanned aerial vehicles. Shape optimizations for different Reynolds numbers and different cost functions are performed by coupling a genetic algorithm with simple panel method flow calculations. The obtained airfoils are presented and compared, whereas the proposed concept is validated by more advanced flow simulations. It appears that improvements in aerodynamic performance of nearly 20% can be expected at Re ranging from 0.05 × 106 to 0.1 × 106. The proposed methodology shows promise and can be applied to different types of lifting surfaces, including wing, tail or propeller blade segments. To check the viability of this method for producing airfoils that can be used in a practical sense, structural analysis of one of the obtained geometries using a simplified 1D finite element method as well as a more detailed 3D analysis are performed. The model is then 3D-printed on a fused deposition modeling (FDM) printer with a polyethylene terephthalate glycol (PETG) filament, and the capability of the airfoil to adequately morph between the two desired geometries is experimentally shown.

AB  - Piezoelectric materials have a wide range of application on the active vibration control of
flexible structures as actuators and sensors due to its inverse and direct piezoelectric effect. In
order to increase performance of active vibration control, piezoelectric fibers are stacked into
single layer composite, making piezoelectric fiber-reinforced composite (PFRC) actuator and
sensor. These actuators and sensors are used for active vibration control of a thin-walled
structures, placing them at the surface of the structure. Since that, control performances depend
on sizes, positions and orientations of PFRC actuators and sensors. The aim of this paper is to
investigate the effect of PFRC actuator orientation and position (top or bottom) on controllability
of cross-ply and angle-ply antisymmetric composite plates for active vibration control. Depending
on layers' orientation, composite laminates possess coupling behavior (bending-stretching,
bending-shear coupling). Since antisymmetric laminates possess bending-stretching coupling
behavior, the effect of this behavior on controllability will be also discussed.

AB  - This paper presents experimental determination effectiveness of active vibration control system depending on
sensor location. The active structure consists of an composite beam as the host structure, strain gages as the sensors
and piezoceramic patch as the actuation element. The Wheatstone bridge, sensor platform, is used to measure the strain
of mechanical system which represents the control signal in system. The active vibration control system is controlled by
PID control strategy. Control algorithm was implemented on the PIC32MX440F256H microcontroller platform. For
the experiment two locations for sensor platform are chosen. In order to determine the influence of piezoelectric
ceramic actuator work on sensor (control) signal the tip deflection of beam is measured by high speed camera. The
active vibration control system effectiveness of both sensor and actuator positions are considered. Experimental results
demonstrate that the presented control method is effective for both locations but the stability of the system can be
violated.

AB  - This paper presents a design, development and experimental verification of an active vibration control system of aluminum plate. The active structure consists of an aluminum rectangular plate as the host structure, strain gages as the sensor element and a piezoceramic patch as the actuation element. Based on characteristics of the integrated elements with use of the fuzzy optimization strategy based on the pseudogoal function the optimal orientation of piezoelectric actuator is found, and the whole active vibration control system is designed and developed. The active vibration control system is controlled by proportional-integral-derivative (PID) control strategy. Control algorithm was implemented on the PIC32MX440F256H microcontroller platform. In order to prevent it from negative occurrences from derivative and integral terms in a PID controller, the first-order low-pass filters are implemented in the derivative action and in the feedback of integral action. The experiment considers active damping control under periodic excitation. Experiments are conducted to verify the effectiveness of the vibration suppression and to compare the damping effect with different adjustment of PID gains. Experimental results corresponding to the developed active vibration control system are presented. The system suppresses more than 90% of vibration amplitude, which confirms the high level of effectiveness in vibration active damping at the proposed active structure.

AB  - Piezoelectric actuators and sensors have a wide range of application in the active vibration control of flexible
structures. Control performances of the smart structures depend on the size and position of piezoelectric actuators and
sensors on a smart structure. This paper deals with the optimization of sizing, location and orientation of piezoelectric
actuators-sensors pairs on thin-walled composite plate. Optimization criteria are based on eigenvalues of the
controllability Grammian matrix. The optimization problem is formulated by integration of finite element method based
on the third-order shear deformation theory and the particle swarm optimization method. Numerical examples are
provided for symmetric cross ply cantilever quadratic composite laminates. Linear quadratic regulator has been
implemented for active vibration control of the composite plates with the optimized piezoelectric actuator-sensor pairs
in order to show the efficiency of presented optimization method.

AB  - This paper deals with active free vibrations control of smart composite beams using particle-swarm optimized self-tuning fuzzy logic controller. In order to improve the performance and robustness of the fuzzy logic controller, this paper proposes integration of self-tuning method, where scaling factors of the input variables in the fuzzy logic controller are adjusted via peak observer, with optimization of membership functions using the particle swarm optimization algorithm. The Mamdani and zero-order Takagi-Sugeno-Kang fuzzy inference methods are employed. In order to overcome stability problem, at the same time keeping advantages of the proposed self-tuning fuzzy logic controller, this controller is combined with the LQR making composite controller. Several numerical studies are provided for the cantilever composite beam for both single mode and multimodal cases. In the multimodal case, a large-scale system is decomposed into smaller subsystems in a parallel structure. In order to represent the efficiency of the proposed controller, obtained results are compared with the corresponding results in the cases of the optimized fuzzy logic controllers with constant scaling factors and linear quadratic regulator.

AB  - Piezoelectric actuators are widely used in structural systems for active vibration
control with the aim to enhance the performance of systems. In order to improve the
dynamic characteristics of active system, it is necessary to know the changes in modal
parameters of systems after embedding of piezoelectric actuators. The effectiveness of
chosen piezoelectric actuator on real system is a very important characteristic in order to
determine capabilities of vibrations suppression. This paper presents two experimental
investigations whose aim is to define the input and output parameters for development of
active vibration control system. In the first experiment modal parameters of the thin
rectangular plate with embedding of piezoelectric actuator is determined. The dynamic
behavior of the thin rectangular plate is identified by using the strain gages (full bridge)
sensor. The second experiment is performed aiming to identify the voltage limits of the
controller’s output for the first three natural frequencies of the rectangular plate. The
determined parameters (natural frequencies and control voltage limits of piezoelectric
actuator) represent boundaries which must be satisfied in the process of development of the
active vibration control system.

AB  - This paper presents experimental verification of the active vibration control of a smart cantilever composite beam using a PID controller. In order to prevent negative occurrences in the derivative and integral terms in a PID controller, first-order low-pass filters are implemented in the derivative action and in the feedback of the integral action. The proposed application setup consists of a composite cantilever beam with a fiber-reinforced piezoelectric actuator and strain gage sensors. The beam is modeled using a finite element method based on third-order shear deformation theory. The experiment considers vibration control under periodic excitation and an initial static deflection. A control algorithm was implemented on a PIC32MX440F256H microcontroller. Experimental results corresponding to the proposed PID controller are compared with corresponding results using proportional (P) control, proportional-integral (PI) control and proportional-derivative (PD) control. Experimental results indicate that the proposed PID controller provides 8.93% more damping compared to a PD controller, 14.41% more damping compared to a PI controller and 19.04% more damping compared to a P controller in the case of vibration under periodic excitation. In the case of free vibration control, the proposed PID controller shows better performance (settling time 1.2 s) compared to the PD controller (settling time 1.5 s) and PI controller (settling time 2.5 s).
