Mobile structures of the ground-based robotic complex (RTC) are investigated as an active component formation of an integrated project “object-system”, which is operated in a destabilizing environment. The relevant problem of minimizing the influence of external destabilizing factors on the operation of mobile spatially-distributed structures of the ground-based RTC is stated in the descriptions of the conceptual apparatus of complex, poorly formalized multicomponent technical systems. Following the logic of this approach, the basic principles of distributed control are determined and their applications are implemented in the mobile structures of the ground-based RTC with elements of subsidiarity. The quintessence of the latter is represented by the technology of multi-antenna MIMO systems, which made it possible to determine the trade-offs of using classical transmission methods and strategies for receiving and processing MIMO signals in the multi-sensory channels of the information-control system (ICS) and radio communication with the data transmission system and commands. Given the complexity of performing the stated tasks, a set of technological functions of reducing the influence of destabilizing factors and their practical variations in the algorithms for obtaining the target result are proposed. A situational model of reducing (minimizing) information losses at the output of the information-control system of the ground-based robotic complex under destabilization has been built. Options have been proposed to achieve the target result: integration of structural and parametric adaptation methods, MIMO technologies, code division multiplexing techniques with CDMA channels, taking into account the heterogeneity factor of information exchange channels and the artificial redundancy of the system itself with respect to the number of external interference sources.

Introduction: The problem of designing information control systems for MIMO systems requires a comprehensive analysis of their operational and technological regimes. Artificial intelligence methods can be used to solve problems related to building models and their optimization in conditions of uncertainty when it is necessary to make prompt decisions.Purpose:Developing a methodology for designing an intelligent information control system which would be invariant to various MIMO systems and could promptly synthesize energy-efficient control actions in real time, taking into account the features of these objects.Results:A static model has been developed for a frame-based knowledge base of an information-control system for energy-intensive process plants in dynamic operation modes. It allows you to take into account the number of states of the operating capability of the control object, many states of its operation, and destabilizing factors of various types. An integrated graph is proposed for generalized intellectualization technology of synthesizing energy-saving control actions for MIMO thermal facilities in warm-up mode.Practical relevance: The created knowledge base structure allows you to promptly provide information for modules realizing algorithmic support of an intelligent information and control system, which in turn makes it possible to synthesize energy-efficient control of a MIMO thermal facility in real time. In addition, energysaving control is characterized by a smooth flow of thermal processes, and this leads to increased durability and safety of the equipment operation.

The introduction of information and digital technologies that support and support all technological processes in the field is an urgent need for the development and implementation of such technology. An organisationally complex and financially intensive project is necessary because of the wide variety of economic entities that differ in the size of production, forms of ownership and socio-economic conditions of production. Automated information control system for mobile units agricultural enterprise provides those-Niko-economic performance, optimum capacity utilization through the use of timely and reliable information on technology. Machine and tractor aggregates are appertained as control objects with variable structure, which is explained by possibility of the system formation from tractor or field machines mobile units with various purposes: tillable, cultivatable, sowing, harvesting and etc. This MTA feature was determined creation of digital control systems of two groups of automatic control and management of the basic energy and operational parameters: tractors, machines and vehicles as part of MTA. To the first group are appertained the automatic control system of tractor motor component loading, motion speed, frictional sliding. To the second group – automatic regulation system of operating depth, seed rate, treatment of liquid combined fertilizers and crop protection agents, filling and driving of various MTA. Novelty of researches consists in methodology of the organization of the centralized control and management of various technological processes at carrying out field works.

Abstract The idea of a tendon vibration control system for a beam-like flexible space structure has been proposed. To verify the feasibility of the concept, an experimental tendon control system has been constructed for the vibration control of a flexible beam simulating Large Space Structures (LSS). This paper discusses modeling, identification, actuator disposition, and controller design for the experimental system. First, a mathematical model of the whole system of the beam and tendon actuator is developed through a finite element method (FEM). Second, to obtain an accurate mathematical model for designing a controller, unknown characteristic parameters are estimated by using an output error method. The validity of the proposed identification scheme is demonstrated by good agreement between the transfer functions of the experimental system and an identified model. Then, disposition of actuators is discussed by using the modal cost analysis. Finally, controllers are designed for SISO and MIMO systems. The feasibility of the proposed controller is verified through numerical simulation and hardware experiments.
