Abstract The relevance of the issue of development of efficient motion control systems for highly automated vehicles capable to successfully compete with foreign systems of similar purpose is defined by importance of the issue of creation of competitive high-tech products under modern market economy conditions. The research objective was to scientifically justify the building principles for motion control systems for highly automated vehicles providing directed search for solution options for the issue of multi-criterion optimization in the software and hardware space. The research involved methods of system analysis and modern control theory. The research result is a set or complex of building principles for motion control systems for highly automated vehicles providing minimization of hardware environment while keeping observability of all vehicle state coordinates significant for safe control and their dynamic boundaries, as well as ensuring controllability via the channels of traction, braking and direction. The conceptual core or base of such integrated intelligent control systems is mathematical and programming support (software) of indirect measurements of the parameters of motion and control of traction, brakes and direction adapting to the vehicle state and environment changes.

This paper proposed an integrated scheme for the modeling and control of induction motors in the networked environment. The networked control system (NCS) is built in hierarchical structure, which consists of a networked speed controller and a local controller. In the networked speed controller, fuzzy gain scheduling is applied to guarantee the robustness against communication constraints. Furthermore, a state predictor is designed to compensate the time delay occurred in data transmission from the sensor to the controller, as a component of the networked speed controller. Simulation and experimental results are given to illustrate the effectiveness of the proposed approach.

In the context of digitalization of the most knowledge-intensive sectors of the domestic economy, the development of an industrial training system in the field of electronic instrumentation is of great importance. The key areas of its development with the use of information and communication technologies include the development and improvement of the technological basis for training and retraining of personnel in engineering educational programs. One of the elements of this basis is the service of multi-user remote access via the internet to a high-tech experimental equipment laboratory as a service based on internet of things (IoT) systems. Within the framework of this service, an urgent problem is to increase the functional saturation of automated stands/installations, which is currently characterized by a paucity of scientific research. The purpose of the research is to expand the areas of experimental research carried out in the mode of multiuser remote access based on specialized IoT systems. As a result, a method of multidisciplinary application of specialized IoT systems was developed. This consists of the technical implementation of possibilities for additional research: research into technologies underlying both multi-user distributed measuring and control systems and IoT systems in general; research into technologies used in their end-to-end computer-aided design; research into joint interaction of several geographically distributed automated stands/installations, implemented on the basis of a four level IoT reference architecture. A methodology for the design of multi-user distributed measuring and control systems as specialized IoT systems has also been developed, focused on solving multidisciplinary research problems in an interactive dialogue mode based on single sample of experimental equipment. The methodology mobilizes organizational, technical and methodological support for the process of creating such systems with specified target characteristics. In general, the method and methodology developed open up opportunities for systematically implementing the basic principles of the “Education 4.0” concept in the preparation and retraining of engineering personnel in the field of electronic instrumentation.

The article considers the methodology of ensuring the dependability of information and control systems using multi-purpose maintenance strategies. The relevance of research is due to the need to ensure the functioning of dependable information and control systems in the face of changes in requirements, environmental parameters, and the manifestation of unspecified failures of their components. The methodology is presented at the system level as a combination of the concept of multi-purpose maintenance, as well as the principles of taking into account changes in the information and control system and environment during the life cycle; comprehensive consideration of different types of failures, and the effects of change; multi-purpose maintenance and combines a set of new models and methods for determining the parameters of dependability information and control systems and the choice of parameters for their maintenance procedures. The proposed concept of multi-purpose maintenance is obtained by developing the Fon-Neumann paradigm and is formulated as a concept of building reliable and secure systems from insufficiently dependable components and multi-purpose maintenance on combined strategies in changing conditions and environment. The scope of the proposed concept is applicable in cases where the principles of von-Neumann do not allow building a viable system due to economic, temporal, or other reasons. In this case, the use of principles, methods, and models that are conceptual, extends to information and control systems built using maintained components and system multi-purpose service strategies. The proposed principle of taking into account changes involves the expansion of the classical control circuit of the fault-tolerant system, which response to the fault occurrence as errors and failures. The principle of comprehensive consideration of different types of failures and the effects of change is a continuation of the principles of unity and connection during the procedures of system analysis. It is also a logical continuation of the facet arrangement of fault types and chains of causal relationships from faults and defects to faults, failures, and errors. Within the framework of the proposed methodology, multi-purpose maintenance strategies, a set of options for goals, types, processes, properties, and parameters of information and control systems have been developed, which reduces model uncertainty and justifies practical measures to ensure dependability at different stages of the life cycle.
