Advanced System Development Technologies I
This book covers vibroacoustic monitoring, inertial attitude systems, and control system for device processing in complex objects. Modern approaches to the synthesis of algorithmic support for a strapdown inertial attitude system are considered. The general characteristics of navigation systems and the composition of their inertial measurement unit are given. The methods of initial alignment of the system on a stationary base are described. Particular attention is paid to the attitude kinematic parameters of the body frame and methods of their numerical integration. Picard's methods for integrating the Bortz and Poisson kinematic equations are shown. An algorithm for a strapdown inertial attitude system based on using real signals of high-precision laser gyroscopes is proposed. System simulation was carried out using the proposed algorithmic methods. The relevance of the control system created for the processing device parts in the conditions of automated manufacturing is substantiated. Theoretical studies are presented, and the relation between electrical signals, the level of tool wear, and the main reasons for generating electrical signals are identified. A mathematical model of cutting tool wear control was developed based on measuring the variable component of cutting electromotive force. A control system for processing device parts on computer numerical control machines in automated production conditions has been developed. It allows for recording critical wear and breakage of the cutting tool, performing its dimensional adjustment directly on the device, and carrying out its industrial approval in flexible production systems.

This book is the second in the series Advanced System Development Technologies: Studies in Systems, Decision and Control. As in the previous volume, the sections of the book are grouped into three directions: optoelectronic technologies, medical technologies, and technological support. The prerequisites for solving the problem of increasing the efficiency of mechanical assembly production are presented, based on the creation of a new method and system for technological preparation of small-scale production in instrument engineering, which takes into account the dominant influence of assembly processes on the time and cost of instrument manufacturing. A new structure and sequence for the technological preparation of instrument production with a formalized relationship between machining and assembly production are proposed. A new model of an assembled product in instrument engineering has been developed, taking into account the labor intensity and specifics of assembly, adjustment, and control-measurement operations, as well as methods for automated design of technological assembly processes. Additionally, a functional model for forming the product structure based on the labor intensity of manufacturing assembly units is proposed, allowing for the formulation of a substantiated plan for the production of parts. A mathematical model of the assembly sequence has also been developed, enabling the construction of an assembly sequence considering organizational and technical factors.
Information-Measuring Systems
This book concentrates on virtual IMS with the use of modern information and measurement modeling technologies. Modern IMS can be implemented as: real hardware and software measuring tools; virtual IMS with the use of modern information and measurement modeling technologies, including simulation, mathematical, physical, with extensive use of computer equipment for conducting a simulation measurement experiment. Compared to real ones, virtual IMS has a number of advantages, and their implementation requires less time, production, and financial costs. However, in a number of cases, due to the information uncertainty of the object of measurement, such IMS cannot provide objective and reliable results, and therefore, it is necessary to conduct a full-scale measurement experiment using real systems. The potential capabilities of modern systems at the stage of information development of society have increased significantly, which contributes both to the expansion of the subject areas of their application and their use to increase the efficiency of known and solve new scientific and applied measurement tasks. The authors are in solidarity with other colleagues—specialists in measurements—in the forecasts of the development of IMS. No improvements in measurement information technologies, including computer and intellectual ones, have not led, are not leading, and obviously cannot lead in future to the expansion of the nomenclature of measurements of quantities while there are no corresponding sensors that form primary information during their direct interaction with the research object. Further development of IMS and their use in various fields of science and technology, including quantum metrology and nanotechnology, will largely be determined by the development of new principles of operation and the creation of new types of sensors based on them.
