“…If we interpret the physical system represented by Figure 1 to be a stacked actuator ( Figure 4) bonded rigidly to a mass, then the constants K1 and K2 are given by K1 = ---and K2 = 1w (9) nd Equation (9) allows us to couple the actuator equations to the dynamics of the structure in Figure 49. The modifications in the model to account for the anhysteretic nonlinearity between the polarization and the electric field are described in the following section.…”

The formulation of an optimization problem for the design of a current controlled switching power amplifier to drive a piezoelectric actuator is the subject of this paper. The design is formulated as a continuous optimization problem. A detailed model that includes the anhysteretic nonlinearity between the electric field and polarization is developed and is coupled with a dynamic model of the amplifier. The design specifications are formulated as optimization constraints. The objective function is chosen to be the weight of the inductor. Optimization results are presented to demonstrate the efficiency of the proposed design methodology.

“…A simultaneous optimization considering control and design parameters as optimization variables has also been presented in [1]. Genetic Algorithms (GAs) [2][3] [4], Augmented Lagrangian (ALAG) [5][6] [7], and Sequential quadratic programming (SQP) techniques [8], are usually the selected optimization procedures. In order to speed-up the computation time, the design models are usually based on analytical formulation.…”

This paper presents a novel design methodology for dimensioning optimal power-electronic converters, which is able to achieve the precision of numerical simulation-based optimization procedures, however minimizing the overall computation time. The approach is based on the utilization of analytical and frequency-domain design models for a numerical optimization process, a validation with numerical simulations of the intermediate optimal solutions, and the correction of the analytical design models precision from the numerical simulation results. This method allows using the numerical simulation in an efficient way, where typically less than ten correction iterations are required. In order to demonstrate the performances of the proposed methodology, the calculation of the control parameters for an H-bridge DC-DC converter and the optimal dimensioning of a damped output filter for a buck converter using the proposed approach is presented.

A high-efficiency driving amplifier with small profile for smart actuators is essential for portable actuator devices. In this paper, a detailed optimized design of half-bridge switching circuit to drive smart actuators is described. The mathematical optimization procedure is applied to the traditional circuit design to make the circuit smaller and more efficient. The objective function presented in this paper is to minimize the total weight of the circuit, including heat sink, inductor and bus capacitor. The calculation of the power dissipation of MOSFET is adopted as a critical step to get the suitable heat sink. The optimization results are presented to demonstrate the effectiveness of this method.
