PWM-controlled power stage under several conditions are prone to the coexistence of several stable modes for the same set of parameters. For the majority of applications, it is an undesired behavior; the other modes apart from the “nominal” one are characterized by lower efficiency and should be avoided. We propose a control aiming to suppress the coexisting undesired modes by utilizing periodic sinusoidal modulation of a reference signal. We study the efficacy of the proposed control strategy for different modulation strength levels with a chopper-fed DC drive as the case example of a PWM-driven system exhibiting multistability. The study is performed by means of numerical simulations in the time domain and bifurcation diagrams. The possible pitfalls and features of the proposed control are demonstrated.

The aim of the work is to develop and study the system of automatic voltage stabilization of a three-phase magnetoelectric generator with shunting of the magnetic flux in the conditions of change of rotation speed. The magneto electric generator is intended for use in autonomous installations of small generation of the electric power. The generator is created on the basis of the serial induction electric motor that provides economy of production of a power source. The operating characteristics of the experimental sample of the magnetoelectric generator are presented, which show the possibility of voltage control. A mathematical model of a magneto electric generator with magnetic flux shunting in the rotor coordinate system is presented. The system of automatic voltage stabilization of a three-phase magneto electric generator with magnetic flux shunting in the conditions of robot speed change is considered in the work. The voltage of the generator is controlled by changing the magnetic flux of the working area using the current of the stationary winding of the shunt, powered by direct current. Algorithms for controlling the shunt current and generator voltage based on the method of inverse dynamics problems in combination with the minimization of local functional capabilities of instantaneous energy values are a scientific novelty, providing dynamic decomposition of the system and low sensitivity to parameter changes. The developed control system provides astatic voltage regulation. The quality of generator voltage control when changing the rotor speed within $+15%$ of the nominal value was studied.

Usage of the computational intelligence to create algorithms of the statistical model that describes the electro physical processes at the last stage of the the lightning leader channel movement to the ground, taking into account the possibility of propagation of a counter spark from ground objects has been proposed. This model is based on experimental data on the speed of the lightning leader channel, the electric field strengths necessary for the development of leader channels of negative and positive polarity, etc. The correspondence of this model to the considered processes is confirmed by comparing the results of calculation the probabilities of places destruction by high-voltage discharge of the earth and objects located on it with known experimental data. An example of the model implementation for appreciation of the prognosticated lightning strikes to an object of the critical infrastructure, namely tanks for oil storage, has been presented.

The paper analyzes methods for optimizing the parameters of the distribution function of the dynamic filters” characteristics. Such methods are used in the spectral analysis of random signals during data transmission. A feature of the work is the proposed functional, which is the starting point for solving the problem of optimizing the parameters of the distribution function of the characteristics of narrow-band dynamic filters for the spectral analysis of ergodic random signals using the correlation-filter method. Three problems of optimizing the parameters of the distribution function of the characteristics of narrow-band dynamic filters are considered and methods for their solution are proposed. It is shown that the first two optimization problems have only an asymptotic solution, which significantly limits their practical application. A simplified problem and a method for optimizing the parameters of the distribution function of the characteristics of narrow-band dynamic filters are proposed. The results of solving the optimization problem obtained by the Levenberg-Marquardt method using a software package for mathematical calculations are presented. Promising methods for solving such a problem are neural network, genetic and other intelligent algorithms for solving optimization problems. The results obtained make it possible to set optimal characteristics when designing narrow-band dynamic filters for random signal spectrum analyzers. The results of the study are proposed to be used in communication systems for filtering interference, radar to improve the quality of identifying airborne objects against the background of interference, and in measuring technology when building spectrum analyzers.

The article presents new data on energy indicators, such as specific fuel consumption and power plant energy efficiency. The use of the obtained data makes it possible to establish the dependence of specific energy indicators on the levels of loading of the power unit. The established distribution makes it possible to determine the optimal parameters of the experimental setup and flow rate at different load levels. The highest specific fuel consumption is observed (1189–1297 g/(kWh) and 962–1147 g/kWh)) at the lowest and highest load for different types of fuel. Experimental data show that ethanol-free fuels can generate more electricity to be used when demand is higher.

The paper proposes a technique and a software tool for calculating the force characteristics of a radial active magnetic bearing with an eight-pole stator with a known control law. It is based on the application of the finite element method implemented in a software package for a general technical analysis of physical processes. The procedure for constructing a computational model, electromagnetic analysis, and displaying graphical and numerical results is implemented in the form of a program code in a parametric programming language of the software package itself. The main program created in C++ is a software integrated with it. It performs an interaction between the user and the software package by setting the bearing parameters, the control law and the initial data of a variant parametric analysis of magnetic forces depending on the position of the rotor in active magnetic bearings and control signals. The active magnetic bearing control law is control signals (control voltages) that are applied to electromagnet windings. Their values depend on the current position of the supporting sections of the rotor and, as an option, the instantaneous values of currents in circuits. All specified data are entered into the code for the software package prepared in advance and stored in the main program. After that, an analysis in the complex is launched in a hidden batch mode. The magnetic forces are calculated from the Maxwell tension tensor in a given cloud of points of the rotor position. The force characteristics are dependences of the restoring magnetic forces in the bearing depending on the displacement of the supporting sections of the rotor in two radial directions. They are also rendered in the main program. For the analyzed design variants of active magnetic bearings and control laws, storage in a database is provided with the possibility of subsequent download and display. The results of computational studies to determine the dependences of magnetic forces on rotor displacements for the design of an active magnetic bearing used in an experimental scale model of a turbocompressor of a gas compressor unit with active magnetic bearings are presented. Verification of the integrated software tool was performed by comparing the calculated and experimental data.
