GENERAL METHODOLOGY OF EVALUATION AND SELECTION OF COMPONENTS OF AUTOMATED SYSTEMS

The features of modern control systems are: the multifunctional nature of production; the multi-connectivity of processes and tasks of automated systems; the need to ensure interaction with systems of different levels and the same level, etc. The article discusses the methodology of evaluation and selection of components of automated systems.

ANALYSIS OF EXISTING METHODS FOR MODELING THE IMPACT OF SPACE RADIATION ON THE ELECTRONIC COMPONENT BASE

The paper considers the modeling of radiation effects in design automation tools. Special at-tention is paid to the development of complex functional blocks and microelectronic products based on them, which require ensuring technological independence when creating modern control sys-tems, data processing and communication.

Automatic Control and Regulation Systems for Heat and Power Plants

The modern stringent requirements for fuel efficiency, exhaust gases toxicity and dynamic performance can only be met by equipping thermal power plants with modern control and regulation systems. Thermal power plants based on internal combustion engines have found the greatest application. They are used in different fields --- automobile and railway transport, agricultural, road-building and forestry machines, in ship-building, aviation, stationary power plants. The analysis of the main directions for further improvement of thermal power plants with internal combustion engines and their automated control and regulation systems has been carried out. Among these directions are an expansion of functional capabilities in such systems, improvement of control and regulation processes quality and their use at adaptation of thermal power plants to work on alternative fuels. The important aspects for improvement of thermal power plants with internal combustion engines are the necessity of studying the working processes of engines and their systems in order to decrease the exhaust gases toxicity. The relevance of these systems research is shown and the evaluation of the current level in their development is made. A characteristic feature of modern control and regulation systems of thermal power plants is their widespread construction on modern microprocessor element base The paper was based on the materials of the reports of the all-Russian scientific and technical conference n.a. Professor V.I. Krutov (27.01.2021)

ODEL OF THE SHAPE OF THE CUTTING EDGES OF SPECIAL HOB CUTTERS FOR PROCESSING SHAPED HELICAL SURFACES

The article is devoted to the design process of a special hob cutter for processing helical surfaces, as well as the methodology for studying the shape of cutting edges using modern control and measuring equipment and the development of a model that allows one to study the effect of the number of regrinds on the shape of the processed surface.

Bioprocess Control: Current Progress and Future Perspectives

Typical bioprocess comprises of different unit operations wherein a near optimal environment is required for cells to grow, divide, and synthesize the desired product. However, bioprocess control caters to unique challenges that arise due to non-linearity, variability, and complexity of biotech processes. This article presents a review of modern control strategies employed in bioprocessing. Conventional control strategies (open loop, closed loop) along with modern control schemes such as fuzzy logic, model predictive control, adaptive control and neural network-based control are illustrated, and their effectiveness is highlighted. Furthermore, it is elucidated that bioprocess control is more than just automation, and includes aspects such as system architecture, software applications, hardware, and interfaces, all of which are optimized and compiled as per demand. This needs to be accomplished while keeping process requirement, production cost, market value of product, regulatory constraints, and data acquisition requirements in our purview. This article aims to offer an overview of the current best practices in bioprocess control, monitoring, and automation.

The Stability of a Two-Axis Gimbal System for the Camera

Gimbal or an inertial stabilization platform (ISP) is used to stabilize the line of sight of an object or device that is tracking another object (LOS) with stationary or moving targets or targets moving forward. It can achieve precision when there is isolation between the tracker and the gimbal base. Studying the 2-axis tilt angle to create gimbal stability, especially in a camera, is a compelling subject for the automation field, as it is controlled by modern controllers. This paper presents a two-axis gimbal loop in which the LOS rate is stable, and I proceed to examine the stability of the system to get a better overview of the system properties. Through examining the stability of the system, I can choose from modern control methods to control them. The stability of the system used from the two analysis methods I present below gives me a visual view from the results achieved. The simulation is performed in MATLAB.
