“…In this design approach, the piezoelectric actuator is modeled as a capacitive load for the electric circuit. In order to assess the validity of the results obtained from the optimization algorithm, the optimal designs were compared to a design that was previously obtained by using classical techniques (Lindner et al, 2002a). This hardware design, developed without the use of the optimizer, is referred to here as the nominal design.…”

The integrated modeling and combined optimization of a Recurve actuator and its drive circuit is considered. A finite element model for Euler-Bernoulli beams is developed with appropriate coupling interface to the drive circuit. The finite element model considers appropriate charge variation over the actuator and leads to an energy conservative formulation. The actuator model is coupled to the electric circuit model via a charge-voltage transfer function. The drive circuit is based on a half-bridge switching amplifier topology. Both actuator and circuit physical design variables are considered in the optimization formulation. The objective is to minimize the weight of the system while satisfying performance and stability constraints. The interactions and trade offs between the actuator and the drive circuit are investigated. Optimization results show clear interrelations between the design of the electric circuit and the actuator.

“…The first step is a DC-DC converter, in this step the input voltage is increased to a relatively high DC voltage. Then in the second step a buck circuit is used to amplify the reference signal [15]. In the first step, the input voltage should be amplified for the second step.…”

The modern technology demands the system to be light and reliable. However, with the conventional vibration control techniques it is difficult to keep the system light with all the damping mechanisms. This work deals with the Active Vibration Control (AVC) of cantilever beam using piezoelectric (PZT) transducers. Active control involves the use of sensors to sense the vibratory motion of the structure, a controller to generate a control signal and an amplifier to amplify the control signal and an actuator which exerts control force on the structure to reduce the vibrations. An experimental setup is made, consisting of the aluminum cantilever beam with the PZT patches mounted on both the sides of the beam. A proportional-integralderivative (PID) controller is designed to generate the required control signal. A high frequency switch mode power converter is designed to generate high voltage required for the actuator to produce the control force. Experiments are performed for the active control of vibration. It is observed that there is reduction in settling time. The experimental results are then verified by the simulation results obtained from MATLAB © .

Smart structures typically consist of many interacting components, which result in a closed loop formed by an actuator, structure, sensors, controller, and drive circuit components. Despite the recognition of component interactions, much of the traditional design approach for such systems is highly compartmentalized and sequential. The primary objective of the present work is to develop a basic understanding of the energy flow and dynamic interaction between the electrical and mechanical subsystems of smart actuators. When operating from portable power sources, a crucial factor in determining the performance of such a smart system is the battery capacity required for the actuator to operate through a given time span along with its life time. The real and reactive power in such a system will determine the battery life and size separately. While the real power is dissipated only in the drive circuit, the reactive power of the circuit and the actuator cannot be calculated individually, where the interaction arises. Multi-objective function optimization problem, which combines the real and reactive power by different weights, will result in a better balanced solution than optimizing either one of them separately. Genetic algorithm is applied for discrete component selection to generate more realistic designs. The optimization result is illustrated in the paper, as well as their relationship with multi-objective functions.
