“…Therefore results of the research [15] can be used for planar antenna synthesis. For the synthesis of planar antennas Trelea's set of parameters is found to produce better result with the convergence speed equal to the Clerc's set of parameters [12]. Therefore w = 0.729, c 1 = 1.494, c 2 = 1.494.…”

“…For the optimization of the TSA profile we propose to use the particle swarm optimization algorithm that has shown to be effective in the planar antenna optimization [12]. The design concept is that the PSO should find such complicated taper profile geometry of the array radiating element that reflections caused by slot line discontinuities, free space boundary and mutual coupling within array scan appear to be compensated in wide frequency band.…”

Paper describes a novel way to optimize the unilateral tapered slot antenna (TSA) being an element of a wideband scanning E-plane linear array. Taper profile of the antenna is mathematically represented as a piecewise linear function. Particle swarm optimization algorithm is implemented to find the coordinates of piecewise linear profile following the purpose to minimize the active reflection coefficient of TSA in a scanning array environment. Active reflection coefficient down to -15 dB is theoretically achieved for TSA in E-plane linear array operating over the most part of frequency band 5-10 GHz and scanning sector ±30°. The proposed design approach is validated by experimental investigations of two linear array test samples with fixed main lobe directions at 0°and 30°respectively. Each test sample is composed from eight similar TSA elements with the optimized piecewise linear profile. Arrays are excited by the 8-way microstrip power divider of corporate type with microstrip true time delay lines at the outputs that provide required wideband phasing of radiating elements.

“…When solving the optimization problem, there is a problem of minimizing the complex nonlinear integral criterion. One of the ways to solve the above problem is to use the ME-PSO method [11,12] or other similar methods. The solution of this problem will make it possible to apply the optimization methods for the motion modes of nonlinear mechanical systems.…”

The article presents a method for solving the problem of eliminating vibrations of the load, which is fixed on a rigid articulated suspension at the time of simultaneous movement of two links of the boom system. The essence of the method is to optimize the mode of simultaneous movement of two links of the boom system of the loader crane with horizontal movement of the load during the start-up period. The problem is solved according to two optimization criteria, namely: according to the optimization criterion of the root-mean-square value of the generalized force and the optimization criterion of the root-mean-square value of the power of drive mechanisms. The developed criteria reflect the undesirable properties of the links of the boom system and drive mechanisms, so their value was minimized. The solution of the optimization problem is presented in a discrete form. For this purpose, the particle swarm optimization (ME-PSO) method was used. This helped to obtain discrete values of the kinematic and power characteristics of the boom system of the loader crane. Since the optimization criterion is an integral functional, the methods of the calculus of variations are used for its optimization. The solution of the variational optimization problem is presented in the form of many parametric functions that satisfy the boundary conditions of motion and minimize the obtained dimensionless criteria. For this purpose, the particle swarm optimization (ME-PSO) method was used. This made it possible to obtain the dependence of the optimal energy and power characteristics of the boom system and the drive mechanisms of the loader crane. The mode of movement of the boom system links obtained as a result of optimization improved the power and energy characteristics of the loader crane, which made it possible to increase its reliability and productivity.
