An overview of modern synchronous reactive and switched reluctance drives is given. Indications are advantages, disadvantages and applications. It is shown that the calculation of losses in the steel of such electric drives for the analysis of operating modes must be performed by the method of loss sharing or by direct calculation of losses from the Maxwell equations. The analytical method for calculating losses in the steel of classical AC machines gives a significant error and is recommended for preliminary calculation of the electric drive at the stage of its synthesis. Verification of simulation results is carried out by comparing them with experimental losses data in an electric drive with a synchronous independent excitation reaction machine. The results of the research can be applied to the design of the electric drive at the stage of calculating the motor by power and carrying out optimization procedures.

This article is devoted to computer modeling of radio systems. The paper shows a method for automated solution of direct and inverse problems of mathematical modeling of nonlinear radio engineering systems. Nonlinear radio engineering systems perform important signal generation and conversion operations: amplification, modulation, detection, frequency multiplication and conversion. Modeling of such systems is necessary to improve the efficiency of their design and research. Existing modeling systems are application packages, that are limited to a set of valid tasks. They usually solve only direct problems (problems of system analysis). Modern radio engineering requires the ability to solve various direct and inverse problems of systems modeling within a uniform program complex. Therefore, the application packages should be replaced by complexes of automated modeling using elements of artificial intelligence. The article proposes a method of using functional grammars to construct the system of automated modeling of nonlinear semiconductor systems. The result of the scientific research is the logical-mathematical model using the terms of functional context-free grammars. The model substantiated by a logical conclusion using lambda calculus. Practical application of the method is demonstrated by examples of solving direct and inverse modeling problems.

The paper presents a new methodological approach to the automated construction of software for solving the design problems of heating systems. The methodological approach is based on the Model-Driven Engineering paradigm. The essence of this paradigm is that the software is generated on the basis of formal description represented by models. The knowledge about heating systems, applied problems, and the applied software is formalized in the form of ontologies. The automated construction of the software system is performed on the basis of a computer model of a heating system, the ontologies and modern metaprogramming technologies. The proposed approach allows us to successfully solve the problem of separation of methods for solving applied problems and models of heating system elements. To this end, the methods are implemented in the form of software components that are not related to properties and models of specific equipment. And the models of heating system elements are automatically compiled into software components. In the process of software system construction, software components that implement models and methods are integrated dynamically. As a result, the software system oriented to solving a specific applied problem is created in an automated mode. The developed approach has been used for the implementation of the SOSNA software. The software is applied to design urban heating systems.

Three-phase thyristor keys are intended to form the in-rush starting currents of electrical equipment with their subsequent shunted electrical apparatus in steady state operation. With reference to transformer substations, they perform shockless connection of the power transformer without generating inrush currents and voltage slump. To extend the functionality of thyristor keys it is proposed, except for shockless connection of the power transformer, to perform its disconnection without arcing between contacts of electrical apparatus, and perform continuous voltage regulation when used by the consumers when changing line voltage. The proposed method and structure for its realization on the basis of three-phase thyristor keys, a twinned reactor and a capacitor bank allows in case of change of the line voltage, simultaneously with the stabilization of the output voltage of a substation, to stabilize the generated reactive power at the input of the substation without creating current distortion in the power transformer and the line.

This paper dwells upon the efficiency of active vibration-protection systems with a controllable rigidity element, which is a linear DC motor (LDCM). For the adopted single-mass simulation model with the paper-mentioned assumption, we have obtained mathematical models written as transfer functions (TF) for the disturbance/control channel. Based on the formulas derived, we generated structural diagrams to study the properties of closed and open systems. We designed the structure of an active closed vibration-protection system including an LDCM, a controllable converter, a controller, and an acceleration sensor for the protected object. The system was modelled mathematically. A controller was synthesized with due account of the required dynamic properties of this closed system. We further tested this system for efficiency and drafted guidelines on its use.

A special feature of tracking control system is to ensure the accuracy of the control set in dynamic modes. The presence of non-linearities in the control object, in the system drives, and especially the non-stationarity of the parameters of the system as a whole makes it difficult to achieve the desired quality indicators using standard classical control algorithms. The paper deals with a new approach to the implementation of fuzzy servo control systems. At the same time, a special emphasis is placed on building the tracking control system. This principle of building an intelligent system not only expands the functionality in the implementation of corrective control action, but also makes it possible to provide self-adjustment of the controller under the selected optimization criteria. This approach is considered on an example of the tracking system model on the basis of the DC electric drive at working off difficult in form of changing signal.

Methods of solution of a problem of an estimation of uncompensated errors of the measurements caused by presence of noises and interferences, that not submitting to statistical regularities are investigated. The model of the signal presented in the form of a composition multiparameter quasidetermined model function and fixed on interval of measurement a background function is considered. The background function is described by an arbitrary ensemble of functions whose range of variation is limited by the E-layer. The proposed model provides the calculation of interval estimates of signal parameters for confidence values close to unity. The technique of calculation of interval errors of parameters on the basis of model of E-areas and nonlinear model function is described. This technique allows calculating interval estimations of parameters for a particular of a signal realization, provided that the range of values of the background function is limited. It is shown that defined in the space of parameters E-regions characterize the state of the control object. Based on the developed algorithm for diagnosing the state of an object from the particular signal realisation using E-regions in the space of parameters of a model function, an approach to identifying abnormal situations is proposed.

Radio-over-Fiber system scheme is described in the paper, the radio domain of this system is performed in the range 75–110 GHz (W-band). Optical signal with given orbital angular momentum (OAM signal) generation method in RoF fiber optic domain is suggested. The method is based on applying two independent lasers, performing at close wavelengths and the device for spatial phase modulation. For simulation and system parameters calculating, mathematical model of OAM signal envelope is suggested based on simplified wave equations system. Computer simulation of these signals envelope during its transmission was performed. It is shown that distortion of transmitted signals arises because of wavelengths difference. Recommendations were developed for constructing fiber-optic components of the system (including a radio-optical converter) designed to minimize this distortion.
