This paper presents a control solution to damp the torque oscillations that appear in a generator during an unbalanced stator fault. The solution proposed is applicable to a multichannel configuration where a generator with several stators is commanded by parallel-connected power converters. The multichannel structure is introduced by some authors with the goal of increasing the reliability of high-power...
It presents the design and implementation of a manufacturing system integrating information and control technologies to provide an access to the user into part of the production system. A distributed control system is structured using didactic plants which emulate a manufacturing system of soft drinks. The control system is developed in Codesys®, integrating its operation through a monitoring system...
The questions of training simulators development technique for oil and gas industry automation control systems are considered. The possibility of using this technique for control systems based on mathematical and algorithmic control models is introduced. A mathematical model is used. The training simulator operating result is the process studying, learning management skills, adjusting parameters to...
The need to improve the quality of management at minimum costs, the complexity of the structure of the management object, the functions performed by it, leads to an increase in uncertainties that need to be taken into account.
The importance of mobile robots for the nuclear disaster response has been realized after Fukushima Dai-ichi nuclear power plant accident. In this paper, we propose a tracked robot for rescue and search in nuclear environment. A gamma-ray irradiation test of the robot's control system is conducted, in order to evaluate the performance of the robot in nuclear environment. The parallel test method is...

Electrical power from solar conversion meets the user loads and the surplus used for water electrolysis to produce hydrogen. Control system is ensured via feed bucks control loops. MPP Tracking regulates with...
Application of ANNs as a tool in proposed techniques has been developed. ANNs model of desired region's border allows to get more available information on the performance indices' behavior in the vicinity of the border. Enclosed in ANNs-model output calculation of recommended value for scanning step norm and of the performance indices gradient enables the use of ANNs-model as a source of important...
The need to improve the quality of management at minimum costs, the complexity of the structure of the management object, the functions performed by it, leads to an increase in uncertainties that need to be taken into account. The use of fuzzy logic to control pumping equipment will reduce the likelihood of erroneous decisions, which will increase the life of technological equipment.
The need to improve the quality of management at minimum costs, the complexity of the structure of the management object, the functions performed by it, leads to an increase in uncertainties that need to be taken into account. Application of typification and unification will allow to reduce the cost of production of new products, to increase the level of automation of productions.
The necessary conditions for detecting and localizing the faults in control systems with a complicated structure are suggested. It is shown that the topological conditions do not depend on the class of operators of the dynamic model of the control system and are verified using path search algorithms in directed graphs. The fault localization algorithm is reduced to the construction and analysis of...
The necessary conditions for the diagnosability of control systems with a complex structure are given. It is shown that the topological conditions for detectability and localization of the fault signal do not depend on the class of operators of the dynamic model of the control system and are checked by using path search algorithms in directed graphs.
In this paper, we explore the capability of selectively decentralized Q-learning approach in learning how to optimally stabilize control systems, as compared to the centralized approach. We focus on problems in which the systems are completely unknown except the possible domain knowledge that allow us to decentralize into subsystems. In selective decentralization, we explore all of the possible communication...
Design of a control module for millimeter wave imaging system based on FPGA is presented in this paper. There are four parts in the module: scanning control module of antenna array, data acquisition and storage control module, ethernet transmission control module and mechanical scanning platform control module.
A power quality measurement system has been developed to analyze harmonics up to 500kHz. The frequency estimation unit of that system, consisting of a frequency shifting unit and a PI controller, was being disturbed by interharmonics at low frequencies, such as ripple control signals. To increase the robustness towards these, the interferences have been modeled. Subsequently, requirements for a digital...

The paper describes the voltage control technique of squire-cage induction machines supplied by a current source inverter. The control system is based on new transformation of the electric drive system (machine and inverter) state variables to the multi-scalar variables form. The backstepping approach is used to obtain the feedback control law. The control system contains the structure of the observer...

Description and function of the main components in the structural diagram of the system are presented. Step-by-step algorithm of the control system for passenger traffic registration in public transport of “smart” city with specific explanation of...
According to Forbes collected data, the public cloud services market will rise in 2016 and is expected to grow to $105 billions and, in fact, Virtual Machines (VMs) are one of the most popular tools for building “Cloud” services. But in service delivery such composition of multiple components greatly complicate analysis of product quality, especially if it is about Voice over IP (VoIP) set of services,...
This paper is devoted to the theoretical and experimental investigation of control system of triode high voltage glow discharge electron gun. Control system consists on two connected depended parts: system of gas-dynamic control of the gas pressure in the discharge gap and system of electric control of beam power. These two systems have been realized as one complex control system. Main theoretical...
This paper considers the game-theoretic pursuit-evasion problem, where a group of pursuers is required to capture a moving target in airspace in the conditions of random perturbing wind actions. As participants of the game we assume the unmanned flight vehicles (FVs), which mathematical models are determined by transfer functions that describe the double-circuit control system with autopilot and settings...
