The paper proposes a general approach to the development of neural network algorithms for determining the values of signal parameters in radio-electronic, telecommunication, and information systems from the functional level to the level of nano-elements; the approach is based on the principles of data, image, and signal recognition. Implementation of this general approach is illustrated by a neural...
Consideration was given to construction of a robust control law for a class of scalar nonlinear dynamic plants under conditions of uncertainty and saturation of a control signal. The synthesis of the control law relies on the hyperstability criterion, L-dissipativity conditions and using in the main circuit an explicit reference model with two outputs and low-inertia filter-corrector.
Actually, the research of phase-lock motor drives is carried out with use of methods of the nonlinear control systems theory. These methods are rather difficult for calculations. The authors make the assumption of use of digital control systems methods for the analysis of the electric drive in a certain area of shaft speed. Digital control systems methods allow to simplify calculations and to receive...
Synchronic-in-phase electric drive is widely used in thermal-imaging and laser scanning systems due to high accuracy characteristics in the wide range of angular speed regulation. The point of the article is to examine the application features of impulsive phase-frequency discriminator with extended functional abilities by implementation of different methods of electric drive control with phase synchronization...
Molecular dynamics is used in this work to study the energy transport through the CuAu crystal lattice by discrete breathers (DBs) with frequencies above the phonon spectrum. The DB moves along the close packed atomic row in the Cu sublattice. An asymmetry was introduced in the initial conditions used for DB excitation in order to set the DB in motion. The maximal distance travelled by the DB was...
Internal combustion engine start processes in Hybrid Electric Vehicles (HEVs) are accompanied by large currents in the windings of electrical machines. It can lead to insulation overheating and fault operation mode. Induction squirrel-cage machine is one of the best AC machines for HEVs. The high efficiency of HEV induction machine with compact stator winding form is proposed. Its stator electrical...
In this paper transformer rectifier units with magnetic cores made from amorphous steel are investigated. The features of the use of amorphous alloys are shown and their comparative analysis is carried out. Calculations of two types of transformer rectifier units with a magnetic core made from various amorphous steels are made. According to the results of calculations experimental samples are made...
